What is the MOST likely cause of the developer’s access issue?
The access permissions to the developer’s AWS CLI binary file have changed.
The permission set that is assumed by IAM Identity Center does not have the necessary permissions to complete the API call.
The credentials from the IAM Identity Center federated role have expired.
The developer is attempting to make API calls to the incorrect AWS account.
Explanations:
The permissions of the AWS CLI binary file would not affect the access to AWS services, as the error indicates issues with permissions at the AWS account level, not file permissions on the local machine.
While it is possible that the permission set does not have the necessary permissions, this option does not address the primary issue of access denied errors occurring after initial successful configuration, which is more likely related to session expiration or role changes.
IAM Identity Center sessions can expire, and if the developer’s credentials have expired, it would lead to Access Denied errors when making API calls. Users need to re-authenticate after their session expires to obtain new credentials.
While making calls to the incorrect AWS account could lead to Access Denied errors, it is less likely since the developer had access previously. Access Denied errors due to account misconfiguration would typically appear consistently rather than only after a certain period.
As I understand it, the answer is:
The credentials from the IAM Identity Center federated role have expired.
In my experience, the answer is:
The credentials from the IAM Identity Center federated role have expired.
