## Title

    Proposed fix: [langchain-aws ChatBedrockConverse] "No 'output' key found in the response from the Bedrock Converse API" — endpoint_url/region misconfigured (non bedrock-runtime endpoint)

## Body

    Recommended action: Use https://bedrock-runtime.<region>.amazonaws.com (or a gateway that proxies Converse verbatim) and matching region_name.
    
    Option: Fix endpoint_url/region [evidence: official_recommended_action]
    Steps:
    1. Remove custom endpoint_url or set it to bedrock-runtime.<region>.amazonaws.com.
    Expected: Response parsed.
    
    Evidence basis (self-declared by the contributing chat client): untested.
