Troubleshooting Amazon Step Functions identity and access

Use the following information to help you diagnose and fix common issues that you might encounter when working with Step Functions and IAM.

I am not authorized to perform an action in Step Functions

If you receive an error that you're not authorized to perform an action, your policies must be updated to allow you to perform the action.

The following example error occurs when the mateojackson user tries to use the console to view details about a fictional my-example-widget resource but does not have the fictional states:GetWidget permissions.

User: arn:aws-cn:iam::123456789012:user/mateojackson is not authorized to perform: states:GetWidget on resource: my-example-widget

In this case, Mateo's policy must be updated to allow him to access the my-example-widget resource using the states:GetWidget action.

If you need help, contact your Amazon administrator. Your administrator is the person who provided you with your sign-in credentials.

I am not authorized to perform iam:PassRole

If you receive an error that you're not authorized to perform the iam:PassRole action, your policies must be updated to allow you to pass a role to Step Functions.

Some Amazon Web Services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.

The following example error occurs when an IAM user named marymajor tries to use the console to perform an action in Step Functions. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the role to the service.

User: arn:aws-cn:iam::123456789012:user/marymajor is not authorized to perform: iam:PassRole

In this case, Mary's policies must be updated to allow her to perform the iam:PassRole action.

If you need help, contact your Amazon administrator. Your administrator is the person who provided you with your sign-in credentials.

I want to allow people outside of my Amazon Web Services account to access my Step Functions resources

You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.
