Recommended action: Refresh credentials first; if current, confirm IAM permissions on the identity actually used and that the model is enabled for the account and region; check aws sts get-caller-identity for a stale AWS_PROFILE. Option: Refresh credentials first; if current, confirm IAM permissions on the identity actually used and that the model is enabled for the account and region; check aws sts get-caller-identity for a stale AWS_PROFILE. [evidence: official_recommended_action] Applies when: Bedrock requests with an expired token, missing IAM permission, or model not enabled Steps: 1. Refresh AWS credentials (awsAuthRefresh command or SSO/keys) 2. aws sts get-caller-identity to confirm the identity (stale AWS_PROFILE is common) 3. Attach required Bedrock IAM permissions 4. Enable the model for the account+region in the Bedrock console Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
