Troubleshooting Amazon Lex identity and access
Use the following information to help you diagnose and fix common issues that you might encounter when working with Amazon Lex and IAM.
Topics
I am not authorized to perform an action in Amazon Lex
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 IAM user
tries to use the console to view details about a fictional
my-example-widgetlex: permissions.GetWidget
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: lex:GetWidgeton resource:my-example-widget
In this case, the policy for the mateojackson user must be updated to allow access to the
my-example-widgetlex: action.GetWidget
If you need help, contact your AWS 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 Amazon Lex.
Some AWS 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
Amazon Lex. 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:iam::123456789012:user/marymajoris 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 AWS administrator. Your administrator is the person who provided you with your sign-in credentials.
I want to allow people outside of my AWS account to access my Amazon Lex 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.
