AWS API request failed with AccessDeniedException

AccessDeniedException

AWS rejected the request because the caller is not authorized to perform the action, often due to IAM policy, resource policy, or missing permissions.

Observed message

AccessDeniedException

Why it happens

  • The IAM identity does not have permission for the requested action.
  • A resource policy explicitly or effectively blocks access.
  • The request targets a resource or account context the caller is not allowed to use.

How to fix it

  1. Inspect the denied action and resource in the error details.
  2. Update IAM or resource policy so the caller can perform the required action.
  3. Retry only after permissions changes have propagated.
