Troubleshooting Amazon Service Catalog identity and access
Use the following information to help you diagnose and fix common issues you might encounter when working with Amazon Service Catalog and IAM.

I am not authorized to perform an action in Amazon Service Catalog
If the Amazon Web Services Management Console tells you that you're not
                authorized to perform an action, then you must contact your administrator for
                assistance. Your administrator is the person that provided you with your sign-in credentials. 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 aws:GetWidget permissions. 
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: aws:GetWidget on resource: my-example-widget
In this case, Mateo asks his administrator to update his policies to allow him to
                access the my-example-widget resource using the aws:GetWidget action.
I am not authorized to perform
                    iam:PassRole
            If you receive an error that you're not authorized to perform the
                iam:PassRole action, then you must contact your administrator for assistance. Your
                administrator is the person that provided you with your user name and password. Ask
                that person to update your policies to allow you to pass a role to Amazon Service Catalog.
Some Amazon 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 a user named marymajor tries to use the console to perform an action in Amazon Service Catalog. However, the action requires the service to have permissions granted by a service role. Mary does not have permissions to pass the role to the service.
User: arn:aws:iam::123456789012:user/marymajor is not authorized to perform: iam:PassRole
In this case, Mary asks her administrator to update her policies to allow her to perform the iam:PassRole action.
I want to allow people outside of my Amazon account to access my Amazon Service Catalog 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.
