Common errors and how to fix them
- Telegram node error “chat not found”: Check chat ID format; it should start with ‘@’ for channels or be a numeric ID. Confirm bot is added to the chat and has permission to send photos.
- uProc returns empty or error: Verify that uProc API Key is active and correctly entered. Check URL format for issues and ensure API rate limits are not exceeded.
Customizations to consider
- Change the website URL in the uProc node to monitor different pages.
