openclaw - 💡(How to fix) Fix Bonjour/CIAO cancellation crashes gateway on startup [1 comments, 2 participants]

TL;DR

Wrap CIAO operations in try/catch blocks or register cancellation-specific rejection handlers to prevent unhandled promise rejections from crashing the gateway.

Guidance

• Identify and patch the specific lines of code in extensions/bonjour/index.js and unhandled-rejections-*.js where CIAO probing/announcement cancellations are not handled, to catch these errors as non-fatal.
• Register cancellation-specific rejection handlers for CIAO operations to prevent them from crashing the gateway.
• Consider implementing a fallback or retry mechanism for mDNS operations to improve robustness on complex networks.
• Verify that the patched code correctly handles CIAO cancellation errors without crashing the gateway.

Example

try {
  // CIAO probing/announcement code here
} catch (error) {
  if (error.message.includes('CIAO PROBING CANCELLED') || error.message.includes('CIAO ANNOUNCEMENT CANCELLED')) {
    // Handle cancellation error as non-fatal
  } else {
    // Re-throw or handle other errors as usual
  }
}

Notes

This fix assumes that the ciao library is correctly implemented and that the issue is solely due to unhandled promise rejections. Additional debugging may be required if the issue persists after applying the suggested fix.

Recommendation

Apply the workaround by wrapping CIAO operations in try/catch blocks or registering cancellation-specific rejection handlers, as this is a more targeted and safer approach than attempting to upgrade or modify the underlying ciao library.
