openclaw - 💡(How to fix) Fix Silent failure in fs.appendFile causes missing messages in session transcripts [1 comments, 1 participants]

1. Observability: Replace silent catches with structured logging (console.error) to allow diagnostics.

TL;DR

Replace silent catches with structured logging to allow diagnostics and consider implementing an asynchronous write-queue to improve reliability.

Guidance

• Identify and replace all instances of empty .catch(() => {}) blocks in the affected file (/usr/lib/node_modules/openclaw/dist/src-DWyil3X5.js) with structured logging using console.error to log errors.
• Implement an asynchronous write-queue (Singleton) to decouple transcription from the main turn execution loop, allowing for buffered writes and reducing the likelihood of failed writes due to high latency or filesystem contention.
• Consider introducing model-agnostic monotonically increasing sequence IDs to enable the UI to detect and highlight missing gaps in conversation history.

Example

// Replace empty catch block with structured logging
fs.appendFile('file.jsonl', data, (err) => {
  if (err) {
    console.error('Error appending to file:', err);
  }
});

Notes

The suggested fixes assume that the issue is primarily caused by silent failures in the transcription layer. However, the root cause may be more complex, and additional debugging may be necessary to fully resolve the issue.

Recommendation

Apply workaround by replacing silent catches with structured logging and implementing an asynchronous write-queue, as this will provide immediate improvements in observability and reliability.
