Can't add feeds

[ghost]

I've set up Spodcast following your tutorial and I think I've set all permissions correctly. www-data can run spodcast.

When adding a url via the web interface, the spinner just disappears after a while and the page stays empty.

I've set "LOG_LEVEL":"DEBUG" and ran the following command as user www-data:

spodcast -c /mnt/audio/spodcast/spodcast.json --max-episodes 1 https://open.spotify.com/show/1OLcQdw2PFDPG1jo3s0wbp

Spodcast seems to find the podcast episode but skips it for some reason. Any help or direction is greatly appreciated!
This is the console output:

I've switched from Debian 11 to Ubuntu 22.04. Now I can still NOT add podcasts via web interface, however adding them via CLI does work. I will close this issue for now and maybe open a new one if I can't fix the web interface issue.
