## Title

    Proposed fix: [Claude Code on Claude Platform on AWS / Bedrock Mantle] 'AWS credentials expired or invalid · ... API Error: 401'

    Option: Run the awsAuthRefresh command named (e.g. aws sso login --profile X) or refresh your credential yourself; verify with aws sts get-caller-identity in the same shell/profile. [evidence: official_recommended_action]
    Applies when: Requests after the AWS SSO session/token expires
    Steps:
    1. aws sso login --profile <profile> in another terminal (or /login -> 3rd-party platform -> refresh credentials)
    2. Retry
    3. If it repeats, run aws sts get-caller-identity with the same AWS_PROFILE
    Expected: The error no longer appears.
