Gateway crashes into infinite restart loop due to Unhandled Promise Rejection on LLM API failure
증상
When the LLM API call fails (e.g., due to an unauthorized model or 404/403 error), an Unhandled Promise Rejection occurs. This crashes the entire OpenClaw Node.js gateway process instantly, often leaving zombie processes that cause infinite restart loops.
원인
Authentication credential mismatch, expiry, or permission scope gap between the requesting agent and the target API.
