RSS feed 500 Internal Server Error #2485

Closed Ylawy closed 3 months ago

Ylawy commented 3 months ago

Describe the bug When I try to access the rss feed for one of my tags I'm getting a 500 Internal Server Error.

I'm using Ubuntu 24.04 LTS with docker-compose. Fresh install of the entire machine and only changedetection is deployed.

Version v0.45.26 and v0.45.25

This is directly from the log files when accessing the rss feed:

without seeing the URLs for the watches in that tag (as the issue template says that you must include!) we cant do anything

you can try add a temporary tag to some watches and find out which one

but without more information, there's nothing that can be done
