Interface SfnAsyncClient

All Superinterfaces:
AutoCloseable, AwsClient, SdkAutoCloseable, SdkClient
@Generated("software.amazon.awssdk:codegen") @ThreadSafe public interface SfnAsyncClient extends AwsClient
Service client for accessing AWS SFN asynchronously. This can be created using the static builder() method.The asynchronous client performs non-blocking I/O when configured with any SdkAsyncHttpClient supported in the SDK. However, full non-blocking is not guaranteed as the async client may perform blocking calls in some cases such as credentials retrieval and endpoint discovery as part of the async API call. Step Functions

Step Functions is a service that lets you coordinate the components of distributed applications and microservices using visual workflows.

You can use Step Functions to build applications from individual components, each of which performs a discrete function, or task, allowing you to scale and change applications quickly. Step Functions provides a console that helps visualize the components of your application as a series of steps. Step Functions automatically triggers and tracks each step, and retries steps when there are errors, so your application executes predictably and in the right order every time. Step Functions logs the state of each step, so you can quickly diagnose and debug any issues.

Step Functions manages operations and underlying infrastructure to ensure your application is available at any scale. You can run tasks on Amazon Web Services, your own servers, or any system that has access to Amazon Web Services. You can access and use Step Functions using the console, the Amazon Web Services SDKs, or an HTTP API. For more information about Step Functions, see the Step Functions Developer Guide .

If you use the Step Functions API actions using Amazon Web Services SDK integrations, make sure the API actions are in camel case and parameter names are in Pascal case. For example, you could use Step Functions API action startSyncExecution and specify its parameter as StateMachineArn.

    • createActivity

      default CompletableFuture<CreateActivityResponse> createActivity(CreateActivityRequest createActivityRequest)

      Creates an activity. An activity is a task that you write in any programming language and host on any machine that has access to Step Functions. Activities must poll Step Functions using the GetActivityTask API action and respond using SendTask* API actions. This function lets Step Functions know the existence of your activity and returns an identifier for use in a state machine and when polling from the activity.

      This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.

      CreateActivity is an idempotent API. Subsequent requests won’t create a duplicate resource if it was already created. CreateActivity's idempotency check is based on the activity name. If a following request has different tags values, Step Functions will ignore these differences and treat it as an idempotent request of the previous. In this case, tags will not be updated, even if they are different.

      Parameters:
      createActivityRequest -
      Returns:
      A Java Future containing the result of the CreateActivity operation returned by the service.
      The CompletableFuture returned by this method can be completed exceptionally with the following exceptions. The exception returned is wrapped with CompletionException, so you need to invoke Throwable.getCause() to retrieve the underlying exception.
      • ActivityLimitExceededException The maximum number of activities has been reached. Existing activities must be deleted before a new activity can be created.
      • InvalidNameException The provided name is not valid.
      • TooManyTagsException You've exceeded the number of tags allowed for a resource. See the Limits Topic in the Step Functions Developer Guide.
      • SdkException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
      • SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc.
      • SfnException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.

    • createStateMachine

      default CompletableFuture<CreateStateMachineResponse> createStateMachine(CreateStateMachineRequest createStateMachineRequest)

      Creates a state machine. A state machine consists of a collection of states that can do work (Task states), determine to which states to transition next (Choice states), stop an execution with an error (Fail states), and so on. State machines are specified using a JSON-based, structured language. For more information, see Amazon States Language in the Step Functions User Guide.

      If you set the publish parameter of this API action to true, it publishes version 1 as the first revision of the state machine.

      This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.

      CreateStateMachine is an idempotent API. Subsequent requests won’t create a duplicate resource if it was already created. CreateStateMachine's idempotency check is based on the state machine name, definition, type, LoggingConfiguration, and TracingConfiguration.

    • createStateMachineAlias

      default CompletableFuture<CreateStateMachineAliasResponse> createStateMachineAlias(CreateStateMachineAliasRequest createStateMachineAliasRequest)

      Creates an alias for a state machine that points to one or two versions of the same state machine. You can set your application to call StartExecution with an alias and update the version the alias uses without changing the client's code.

      You can also map an alias to split StartExecution requests between two versions of a state machine. To do this, add a second RoutingConfig object in the routingConfiguration parameter. You must also specify the percentage of execution run requests each version should receive in both RoutingConfig objects. Step Functions randomly chooses which version runs a given execution based on the percentage you specify.

      To create an alias that points to a single version, specify a single RoutingConfig object with a weight set to 100.

      You can create up to 100 aliases for each state machine. You must delete unused aliases using the DeleteStateMachineAlias API action.

      CreateStateMachineAlias is an idempotent API. Step Functions bases the idempotency check on the stateMachineArn, description, name, and routingConfiguration parameters. Requests that contain the same values for these parameters return a successful idempotent response without creating a duplicate resource.

    • deleteStateMachine

      default CompletableFuture<DeleteStateMachineResponse> deleteStateMachine(DeleteStateMachineRequest deleteStateMachineRequest)

      Deletes a state machine. This is an asynchronous operation. It sets the state machine's status to DELETING and begins the deletion process. A state machine is deleted only when all its executions are completed. On the next state transition, the state machine's executions are terminated.

      A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.

      The following are some examples of qualified and unqualified state machine ARNs:

      • The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine.

        arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel

        If you provide a qualified state machine ARN that refers to a Distributed Map state, the request fails with ValidationException.

      • The following unqualified state machine ARN refers to a state machine named myStateMachine.

        arn:partition:states:region:account-id:stateMachine:myStateMachine

      This API action also deletes all versions and aliases associated with a state machine.

      For EXPRESS state machines, the deletion happens eventually (usually in less than a minute). Running executions may emit logs after DeleteStateMachine API is called.

      Parameters:
      deleteStateMachineRequest -
      Returns:
      A Java Future containing the result of the DeleteStateMachine operation returned by the service.

    • deleteStateMachineVersion

      default CompletableFuture<DeleteStateMachineVersionResponse> deleteStateMachineVersion(Consumer<DeleteStateMachineVersionRequest.Builder> deleteStateMachineVersionRequest)

      Deletes a state machine version. After you delete a version, you can't call StartExecution using that version's ARN or use the version with a state machine alias.

      Deleting a state machine version won't terminate its in-progress executions.

      You can't delete a state machine version currently referenced by one or more aliases. Before you delete a version, you must either delete the aliases or update them to point to another state machine version.

    • getExecutionHistoryPaginator

      default GetExecutionHistoryPublisher getExecutionHistoryPaginator(GetExecutionHistoryRequest getExecutionHistoryRequest)

      This is a variant of getExecutionHistory(software.amazon.awssdk.services.sfn.model.GetExecutionHistoryRequest) operation. The return type is a custom publisher that can be subscribed to request a stream of response pages. SDK will internally handle making service calls for you.

      When the operation is called, an instance of this class is returned. At this point, no service calls are made yet and so there is no guarantee that the request is valid. If there are errors in your request, you will see the failures only after you start streaming the data. The subscribe method should be called as a request to start streaming data. For more info, see Publisher.subscribe(org.reactivestreams.Subscriber). Each call to the subscribe method will result in a new Subscription i.e., a new contract to stream data from the starting request.

      The following are few ways to use the response class:

      1) Using the subscribe helper method 
       
 software.amazon.awssdk.services.sfn.paginators.GetExecutionHistoryPublisher publisher = client.getExecutionHistoryPaginator(request);
 CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response });
 future.get();
      2) Using a custom subscriber 
       
 software.amazon.awssdk.services.sfn.paginators.GetExecutionHistoryPublisher publisher = client.getExecutionHistoryPaginator(request);
 publisher.subscribe(new Subscriber<software.amazon.awssdk.services.sfn.model.GetExecutionHistoryResponse>() {
 
 public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
 
 
 public void onNext(software.amazon.awssdk.services.sfn.model.GetExecutionHistoryResponse response) { //... };
 });
      As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.

      Please notice that the configuration of maxResults won't limit the number of results you get with the paginator. It only limits the number of results in each page.

      Note: If you prefer to have control on service calls, use the getExecutionHistory(software.amazon.awssdk.services.sfn.model.GetExecutionHistoryRequest) operation.

      Parameters:
      getExecutionHistoryRequest -
      Returns:
      A custom publisher that can be subscribed to request a stream of response pages.
      The CompletableFuture returned by this method can be completed exceptionally with the following exceptions. The exception returned is wrapped with CompletionException, so you need to invoke Throwable.getCause() to retrieve the underlying exception.
      • ExecutionDoesNotExistException The specified execution does not exist.
      • InvalidArnException The provided Amazon Resource Name (ARN) is not valid.
      • InvalidTokenException The provided token is not valid.
      • SdkException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.

      This is a variant of listMapRuns(software.amazon.awssdk.services.sfn.model.ListMapRunsRequest) operation. The return type is a custom publisher that can be subscribed to request a stream of response pages. SDK will internally handle making service calls for you.

      When the operation is called, an instance of this class is returned. At this point, no service calls are made yet and so there is no guarantee that the request is valid. If there are errors in your request, you will see the failures only after you start streaming the data. The subscribe method should be called as a request to start streaming data. For more info, see Publisher.subscribe(org.reactivestreams.Subscriber). Each call to the subscribe method will result in a new Subscription i.e., a new contract to stream data from the starting request.

      The following are few ways to use the response class:

      1) Using the subscribe helper method 
       
 software.amazon.awssdk.services.sfn.paginators.ListMapRunsPublisher publisher = client.listMapRunsPaginator(request);
 CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response });

      This is a variant of listStateMachines(software.amazon.awssdk.services.sfn.model.ListStateMachinesRequest) operation. The return type is a custom publisher that can be subscribed to request a stream of response pages. SDK will internally handle making service calls for you.

      When the operation is called, an instance of this class is returned. At this point, no service calls are made yet and so there is no guarantee that the request is valid. If there are errors in your request, you will see the failures only after you start streaming the data. The subscribe method should be called as a request to start streaming data. For more info, see Publisher.subscribe(org.reactivestreams.Subscriber). Each call to the subscribe method will result in a new Subscription i.e., a new contract to stream data from the starting request.

      The following are few ways to use the response class:

      1) Using the subscribe helper method 
       
 software.amazon.awssdk.services.sfn.paginators.ListStateMachinesPublisher publisher = client.listStateMachinesPaginator(request);
 CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response });
 future.get();
      2) Using a custom subscriber 
       
 software.amazon.awssdk.services.sfn.paginators.ListStateMachinesPublisher publisher = client.listStateMachinesPaginator(request);
 publisher.subscribe(new Subscriber<software.amazon.awssdk.services.sfn.model.ListStateMachinesResponse>() {
 
 public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
 
 
 public void onNext(software.amazon.awssdk.services.sfn.model.ListStateMachinesResponse response) { //... };
 });
      As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.

      Please notice that the configuration of maxResults won't limit the number of results you get with the paginator. It only limits the number of results in each page.

      Note: If you prefer to have control on service calls, use the listStateMachines(software.amazon.awssdk.services.sfn.model.ListStateMachinesRequest) operation.

    • publishStateMachineVersion

      default CompletableFuture<PublishStateMachineVersionResponse> publishStateMachineVersion(PublishStateMachineVersionRequest publishStateMachineVersionRequest)

      Creates a version from the current revision of a state machine. Use versions to create immutable snapshots of your state machine. You can start executions from versions either directly or with an alias. To create an alias, use CreateStateMachineAlias.

      You can publish up to 1000 versions for each state machine. You must manually delete unused versions using the DeleteStateMachineVersion API action.

      PublishStateMachineVersion is an idempotent API. It doesn't create a duplicate state machine version if it already exists for the current revision. Step Functions bases PublishStateMachineVersion's idempotency check on the stateMachineArn, name, and revisionId parameters. Requests with the same parameters return a successful idempotent response. If you don't specify a revisionId, Step Functions checks for a previously published version of the state machine's current revision.

    • redriveExecution

      default CompletableFuture<RedriveExecutionResponse> redriveExecution(RedriveExecutionRequest redriveExecutionRequest)

      Restarts unsuccessful executions of Standard workflows that didn't complete successfully in the last 14 days. These include failed, aborted, or timed out executions. When you redrive an execution, it continues the failed execution from the unsuccessful step and uses the same input. Step Functions preserves the results and execution history of the successful steps, and doesn't rerun these steps when you redrive an execution. Redriven executions use the same state machine definition and execution ARN as the original execution attempt.

      For workflows that include an Inline Map or Parallel state, RedriveExecution API action reschedules and redrives only the iterations and branches that failed or aborted.

      To redrive a workflow that includes a Distributed Map state whose Map Run failed, you must redrive the parent workflow. The parent workflow redrives all the unsuccessful states, including a failed Map Run. If a Map Run was not started in the original execution attempt, the redriven parent workflow starts the Map Run.

      This API action is not supported by EXPRESS state machines.

      However, you can restart the unsuccessful executions of Express child workflows in a Distributed Map by redriving its Map Run. When you redrive a Map Run, the Express child workflows are rerun using the StartExecution API action. For more information, see Redriving Map Runs.

      You can redrive executions if your original execution meets the following conditions:

      • The execution status isn't SUCCEEDED.

      • Your workflow execution has not exceeded the redrivable period of 14 days. Redrivable period refers to the time during which you can redrive a given execution. This period starts from the day a state machine completes its execution.

      • The workflow execution has not exceeded the maximum open time of one year. For more information about state machine quotas, see Quotas related to state machine executions.

      • The execution event history count is less than 24,999. Redriven executions append their event history to the existing event history. Make sure your workflow execution contains less than 24,999 events to accommodate the ExecutionRedriven history event and at least one other history event.

      Parameters:
      redriveExecutionRequest -
      Returns:
      A Java Future containing the result of the RedriveExecution operation returned by the service.
      The CompletableFuture returned by this method can be completed exceptionally with the following exceptions. The exception returned is wrapped with CompletionException, so you need to invoke Throwable.getCause() to retrieve the underlying exception.

      • ExecutionNotRedrivableException The execution Amazon Resource Name (ARN) that you specified for executionArn cannot be redriven.
      • ExecutionLimitExceededException The maximum number of running executions has been reached. Running executions must end or be stopped before a new execution can be started.
      • InvalidArnException The provided Amazon Resource Name (ARN) is not valid.

    • startExecution

      default CompletableFuture<StartExecutionResponse> startExecution(StartExecutionRequest startExecutionRequest)

      Starts a state machine execution.

      A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.

      The following are some examples of qualified and unqualified state machine ARNs:

      • The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine.

        arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel

        If you provide a qualified state machine ARN that refers to a Distributed Map state, the request fails with ValidationException.

      • The following qualified state machine ARN refers to an alias named PROD.

        arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine:PROD>

        If you provide a qualified state machine ARN that refers to a version ARN or an alias ARN, the request starts execution for that version or alias.

      • The following unqualified state machine ARN refers to a state machine named myStateMachine.

        arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine>

      If you start an execution with an unqualified state machine ARN, Step Functions uses the latest revision of the state machine for the execution.

      To start executions of a state machine version, call StartExecution and provide the version ARN or the ARN of an alias that points to the version.

      StartExecution is idempotent for STANDARD workflows. For a STANDARD workflow, if you call StartExecution with the same name and input as a running execution, the call succeeds and return the same response as the original request. If the execution is closed or if the input is different, it returns a 400 ExecutionAlreadyExists error. You can reuse names after 90 days.

      StartExecution isn't idempotent for EXPRESS workflows.

      Parameters:
      startExecutionRequest -
      Returns:
      A Java Future containing the result of the StartExecution operation returned by the service.
      The CompletableFuture returned by this method can be completed exceptionally with the following exceptions. The exception returned is wrapped with CompletionException, so you need to invoke Throwable.getCause() to retrieve the underlying exception.
      • ExecutionLimitExceededException The maximum number of running executions has been reached. Running executions must end or be stopped before a new execution can be started.
      • ExecutionAlreadyExistsException The execution has the same name as another execution (but a different input).

        Executions with the same name and input are considered idempotent.

      • InvalidArnException The provided Amazon Resource Name (ARN) is not valid.
      • InvalidExecutionInputException The provided JSON input data is not valid.
      • InvalidNameException The provided name is not valid.

    • startExecution

      default CompletableFuture<StartExecutionResponse> startExecution(Consumer<StartExecutionRequest.Builder> startExecutionRequest)

      Starts a state machine execution.

      A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.

      The following are some examples of qualified and unqualified state machine ARNs:

      • The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine.

        arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel

        If you provide a qualified state machine ARN that refers to a Distributed Map state, the request fails with ValidationException.

      • The following qualified state machine ARN refers to an alias named PROD.

        arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine:PROD>

        If you provide a qualified state machine ARN that refers to a version ARN or an alias ARN, the request starts execution for that version or alias.

      • The following unqualified state machine ARN refers to a state machine named myStateMachine.

        arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine>

      If you start an execution with an unqualified state machine ARN, Step Functions uses the latest revision of the state machine for the execution.

      To start executions of a state machine version, call StartExecution and provide the version ARN or the ARN of an alias that points to the version.

      StartExecution is idempotent for STANDARD workflows. For a STANDARD workflow, if you call StartExecution with the same name and input as a running execution, the call succeeds and return the same response as the original request. If the execution is closed or if the input is different, it returns a 400 ExecutionAlreadyExists error. You can reuse names after 90 days.

      StartExecution isn't idempotent for EXPRESS workflows.

      Updates an existing state machine by modifying its definition, roleArn, or loggingConfiguration. Running executions will continue to use the previous definition and roleArn. You must include at least one of definition or roleArn or you will receive a MissingRequiredParameter error.

      A qualified state machine ARN refers to a Distributed Map state defined within a state machine. For example, the qualified state machine ARN arn:partition:states:region:account-id:stateMachine:stateMachineName/mapStateLabel refers to a Distributed Map state with a label mapStateLabel in the state machine named stateMachineName.

      A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.

      The following are some examples of qualified and unqualified state machine ARNs:

      • The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine.

        arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel

      • The following qualified state machine ARN refers to an alias named PROD.

        arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine:PROD>

        If you provide a qualified state machine ARN that refers to a version ARN or an alias ARN, the request starts execution for that version or alias.

      • The following unqualified state machine ARN refers to a state machine named myStateMachine.

        arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine>

      After you update your state machine, you can set the publish parameter to true in the same action to publish a new version. This way, you can opt-in to strict versioning of your state machine.

      Step Functions assigns monotonically increasing integers for state machine versions, starting at version number 1.

      All StartExecution calls within a few seconds use the updated definition and roleArn. Executions started immediately after you call UpdateStateMachine may use the previous state machine definition and roleArn.

      All StartExecution calls within a few seconds use the updated definition and roleArn. Executions started immediately after you call UpdateStateMachine may use the previous state machine definition and roleArn.


      This is a convenience which creates an instance of the UpdateStateMachineRequest.Builder avoiding the need to create one manually via UpdateStateMachineRequest.builder()

      Parameters:
      updateStateMachineRequest - A Consumer that will call methods on UpdateStateMachineRequest.Builder to create a request.
      Returns:
      A Java Future containing the result of the UpdateStateMachine operation returned by the service.
      The CompletableFuture returned by this method can be completed exceptionally with the following exceptions. The exception returned is wrapped with CompletionException, so you need to invoke Throwable.getCause() to retrieve the underlying exception.
      • InvalidArnException The provided Amazon Resource Name (ARN) is not valid.
      • InvalidDefinitionException The provided Amazon States Language definition is not valid.
      • InvalidLoggingConfigurationException
      • InvalidTracingConfigurationException Your tracingConfiguration key does not match, or enabled has not been set to true or false.
      • MissingRequiredParameterException Request is missing a required parameter. This error occurs if both definition and roleArn are not specified.
      • StateMachineDeletingException The specified state machine is being deleted.
      • StateMachineDoesNotExistException The specified state machine does not exist.
      • ServiceQuotaExceededException The request would cause a service quota to be exceeded.

        HTTP Status Code: 402

      • ConflictException Updating or deleting a resource can cause an inconsistent state. This error occurs when there're concurrent requests for DeleteStateMachineVersion, PublishStateMachineVersion, or UpdateStateMachine with the publish parameter set to true.

        HTTP Status Code: 409

      • ValidationException The input does not satisfy the constraints specified by an Amazon Web Services service.
      • SdkException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
      • SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc.
      • SfnException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.

    • updateStateMachineAlias

      default CompletableFuture<UpdateStateMachineAliasResponse> updateStateMachineAlias(UpdateStateMachineAliasRequest updateStateMachineAliasRequest)

      Updates the configuration of an existing state machine alias by modifying its description or routingConfiguration.

      You must specify at least one of the description or routingConfiguration parameters to update a state machine alias.

      UpdateStateMachineAlias is an idempotent API. Step Functions bases the idempotency check on the stateMachineAliasArn, description, and routingConfiguration parameters. Requests with the same parameters return an idempotent response.

      This operation is eventually consistent. All StartExecution requests made within a few seconds use the latest alias configuration. Executions started immediately after calling UpdateStateMachineAlias may use the previous routing configuration.

    • validateStateMachineDefinition

      default CompletableFuture<ValidateStateMachineDefinitionResponse> validateStateMachineDefinition(ValidateStateMachineDefinitionRequest validateStateMachineDefinitionRequest)

      Validates the syntax of a state machine definition.

      You can validate that a state machine definition is correct without creating a state machine resource. Step Functions will implicitly perform the same syntax check when you invoke CreateStateMachine and UpdateStateMachine. State machine definitions are specified using a JSON-based, structured language. For more information on Amazon States Language see Amazon States Language (ASL).

      Suggested uses for ValidateStateMachineDefinition:

      • Integrate automated checks into your code review or Continuous Integration (CI) process to validate state machine definitions before starting deployments.

      • Run the validation from a Git pre-commit hook to check your state machine definitions before committing them to your source repository.

      Errors found in the state machine definition will be returned in the response as a list of diagnostic elements, rather than raise an exception.

      Parameters:
      validateStateMachineDefinitionRequest -
      Returns:
      A Java Future containing the result of the ValidateStateMachineDefinition operation returned by the service.
      The CompletableFuture returned by this method can be completed exceptionally with the following exceptions. The exception returned is wrapped with CompletionException, so you need to invoke Throwable.getCause() to retrieve the underlying exception.
