Slack WebSocket 408 timeout causes unhandled promise rejection + gateway crash
증상
The OpenClaw gateway crashes when the Slack Socket Mode WebSocket connection receives a 408 (Request Timeout) response. An unhandled promise rejection is thrown and the Node.js process exits.
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
Wrapping openclaw-gateway in a watchdog loop (while true; do openclaw-gateway; sleep 5; done) provides auto-restart, but the root cause (unhandled rejection in Slack WebSocket error handler) should be fixed.
