Can't create a playlist in Jellyfin

[mickgotwings]

Getting an error message in the logs:

failed to create playlist: createJfPlaylist(): got 400 from https://...

Refreshing library works fine, so it must not be related to auth. Also, it's a 400, not a 401/403.
Explo is the latest version, Jellyfin is 10.10.5.

Thanks for reporting,
I wasn't able to reproduce this (using 10.10.5 as well), I published a new version which prints out the full response body, when a NOK response code is received. Could you try running Explo again with v0.8.4 and set DEBUG to true in .env

Sure, here you go:

To be fair, I've ran it in test mode, since explo wouldn't find my latest playlist (possible timezone issue or smth).

Also, the output is weird: I haven't got any of those songs neither in my library, nor in my listenbrainz discovery playlist.
I'm pretty sure my .env is valid, but just in case, I'll also put it here for debug:

# Music system you use (emby, jellyfin, mpd, plex or subsonic)
EXPLO_SYSTEM=jellyfin
# Address of music system (required for emby, jellyfin, plex and subsonic)
SYSTEM_URL=https://jellyfin.dockervm.local
# API Key from music server (required for emby, jellyfin)
API_KEY=REDACTED
# Directory where to download tracks (required)
# PS! It's recommended to make a separate directory (under the music library) for Explo
DOWNLOAD_DIR=/music/explo
# Username for ListenBrain recommendations (required)
LISTENBRAINZ_USER=mickgotwings
# Youtube Data API key (required)
YOUTUBE_API_KEY=REDACTED
LIBRARY_NAME=Music

LISTENBRAINZ_DISCOVERY=test
DEBUG=true

Furthermore, I can indeed see the file "You Rock My World-Michael Jackson.mp3" both in the expected folder, and in the Jellyfin library, so it's weird it wasn't found by explo.

UPD: the link to Listenbrainz discovery playlist for convenience: https://listenbrainz.org/playlist/4b2861a7-80e7-448d-ab45-146242b2af8c/

As far as the output goes, the songs are coming from ListenBrainz API, they are still tailored to you, but the API only returns ~25 songs and it updates less often (and test downloads the first available one).

Can you tell me how large your Music library is (approx)? I haven't ran Explo with a large library, so the problem could come from there. Right now Explo (should) query every item in the library and then search for the song based on the output. (tbh I have to come up with a better way to search for songs on Jellyfin).

Could you try making an separate library and change LIBRARY_NAME to the new one. Make sure "Enable real time monitoring" is checked in the library options. After that try running Explo in test mode
