as the the title states...

Here's Jellyscrub booting up:

Btw for reference, it's guessing where the Jellyfin server's files are. I can't point it to the correct folder either, because there is no configuration option.

It's not guessing where the web path is, it uses the web path that is set when Jellyfin is launched. If you are hosting the Jellyfin web files using an external web server (e.g. nginx or Apache) then you must manually copy and paste the script tag into the index file as described in the README.

If you are using the internal Jellyfin server to host the web files then the path should be correct, and you should change the ownership of /app/bin/jellyfin-web/index.html to match the user running the Jellyfin process.
