Description

On macOS, when the network is disconnected (e.g., closing the laptop lid or switching to battery mode without stable Wi-Fi), the Gateway process frequently crashes. This is caused by an Unhandled promise rejection in the Slack plugin (and potentially others).

Impact

Rapid consecutive crashes trigger the macOS launchd throttling mechanism, leading to the service being marked as "Not Loaded" or "Throttled", requiring manual intervention to restore the service.

Expected Behavior

Plugins should catch network-related errors and implement a retry/backoff mechanism instead of allowing the entire process to exit.
