GET http://jellyfin:8096/Library/VirtualFolders returns a html type response

I just did a fresh install of janitorr using the documentation and the default application.yml template.

changed all the secrets, api keys, hosts and ports. janitorr has its own "service account" in jellyfin and all necessary permissions.

Firing up janitorr sadly led to nothing more than a: ERROR 1 --- [ scheduling-1] o.s.s.s.TaskUtils$LoggingErrorHandler : Unexpected error occurred in scheduled task

Whats going on here?

since i was trying to find out the error myself at first i know now that the log msg

feign.FeignException: Unexpected character ('<' (code 60)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false') at [Source: (BufferedReader); line: 1, column: 2] reading GET http://jellyfin:8096/Library/VirtualFolders

is telling me its seeing an < char in the awaited json response and cant process that (obviously...). did a GET http://jellyfin:8096/Library/VirtualFolders with insomnia and got:

<!doctype html> ......... (if requested ill post the rest of that)

since im new to janitorr and didnt see any obvious mistakes of mine (hopefully ;) ) id love to get some insight on what might be the culprit/fix or bug.

thank you in advance feroxib

Can you please share your config with snesitive information redacted?

It seems that that URL is getting an HTML response (could potentially be from reverse proxy or invalid API key), as you've correctly identified. Does the user have access to all necessary libraries? Does your server even run on jellyfin:8096 and is reachable by janitorr under that URL?

When I make a get request wth the right API key to that URL for my server, I get:

Hi thanks for the reply

my config

# File system access (same mapping as Sonarr, Radarr and Jellyfin) is required to delete TV shows by season and create "Leaving Soon" collections in Jellyfin
# Currently, Jellyfin does not support an easy way to add only a few seasons or movies to a collection, we need access to temporary symlinks
# Additionally, checks to prevent deletion on currently still seeding media currently require file system access as well

You didn't really answer any of my other questions. Based on your censoring the jellyfin host, I guess it's public? Try accessing it through the internal host.

I can't see anything obviously wrong, but there must be something wrong elsewhere with your setup. If you access your Jellyfin server, you get SOME form of HTML response and this can only happen if a reverse proxy incorrectly forwards data or you're accessing the wrong server altogether.

One reason could be that it doesn't forward the headers.

Closing this, no response in over a week.
