Node red won't start

Third party integrations Node-RED
1

I have been using Node Red without issues for the past year. All of a sudden Node Red wont start and I get 502 bad gateway message.

I believe this is due to a bug with Huemagic, which I no longer use. How can I remove the palette when I can’t start Node Red?

Fixed. I reverted to a previous backup and removed Huemagic

I am having the very same problem. I am not using anything related to raspberry-pi GPIO, how you guessed how to fix it? Is Huemagic a node-red library? Another addon?

I looked at the error at the end of the log where it says

2 Dec 23:05:55 - [error] Error: Philips Hue: 1, unauthorized user
at /config/node-red/node_modules/huejay/lib/Transport.js:88:17

I would suggest looking in the Node Red log for the first error it throws.
