Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Pass only one auth mode; pin botocore/langchain-aws together if you rely on api_key; unset AWS_BEARER_TOKEN_BEDROCK when you intend profile/role auth.
Option: Use a single auth mode and pin versions [evidence: official_recommended_action]
Steps:
1. Remove api_key when using profiles/roles.
2. Pin botocore to a version tested with your langchain-aws when using api_key.
Expected: Predictable identity; no RuntimeError.
