Troubleshooting
- Database Locks: If you encounter
SQLITE_BUSY, ensure no other process (like a DB viewer) has the file open. The app handles some concurrency but file locks can block it. - API Timeouts: If the API is slow, the app is configured with a 100s timeout and 2 retries. Check your network connection.
- Logs: Check
logs/directory for daily application logs and error snapshots.
