How to Fix It

AWS S3: Validate token/key format, expiration, and environment (test vs live) in the failing request.
2
Re-issue credentials with the minimum required scopes and rotate stale secrets.
3
Confirm account/project status and access policy before retrying the same call.
4
Re-run request with fresh auth artifacts and monitor for repeat failures.
5
Add guardrails in client code to detect and refresh invalid auth state automatically.
