Troubleshooting Amazon Managed Blockchain (AMB) Query identity and access

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

I am not authorized to perform an action in AMB Query

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-widget resource but doesn't have the fictional managedblockchain-query::GetWidget permissions.

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

In this case, the policy for the mateojackson user must be updated to allow access to the my-example-widget resource by using the managedblockchain-query::GetWidget action.

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