Hi @thucar,
Thanks for sharing this extra piece of the puzzle!
This is becoming very annoying. Last week I got a notification of exact the same error, but for my other UI node.
- I assume this error occurs in the Node-RED log, and not in the browser console log (where your dashboard is running)?
- Could you please share the version numbers of NodeJs, dashboard and Node-RED itself. If I understand it correctly, it might be caused by an older NodeJs version, but I have no clue which part of the code eventually triggers that exception ...
