Probably not actually It’s a known Jellyfin bug

Okay, sorry, I really did search and couldn’t find anything. Can I help with troubleshooting?

I took another look. In the Android apps Amcfy Music, Finamp, and Jellify, the artist favorites are displayed. So there must be a way. It might be worth capturing the traffic with Wireshark.

/Artists and /Artists/{name} APIs return different values for IsFavorite

bug

### Description of the bug When using the API to access `UserData` for artists …the API returns different results when accessing the data as a list through `\Artists` and `\Artists\AlbumArtists` that to accessing an individual artist directly through `\Artists\{name}`. Only when accessing the artists information directly using the `\Artists\{name}` API do you get the correct value for `IsFavorite` the other methods always return `False`. ### Reproduction steps The following Python script demonstrates the issue: ``` import requests import os import uuid BASE_URL = 'https://jellyfin.my.domain' auth_data = { 'Username': 'REDACTED', 'Pw': 'REDACTED' } CLIENT = 'fave_not_working_demo' DEVICE = os.uname()[1] DEVICE_ID = f'{uuid.getnode()}-{auth_data["Username"]}' VERSION = '0.0.1' HEADERS = { 'Authorization': \ f'MediaBrowser Client="{CLIENT}", Device="{DEVICE}", DeviceId="{DEVICE_ID}", Version="{VERSION}"' } resp = requests.post(BASE_URL + '/Users/AuthenticateByName', headers=HEADERS, json=auth_data) TOKEN = resp.json()['AccessToken'] HEADERS['Authorization'] += f', Token="{TOKEN}"' with requests.Session() as s: s.headers.update(HEADERS) r = s.get(f'{BASE_URL}/Artists') if r.status_code == 200: for i in r.json()['Items']: rr = s.get(f'{BASE_URL}/Artists/{i["Name"]}') if rr.status_code == 200 and rr.json()['UserData']['IsFavorite']: print('/Artists API ', i['Name'], i['Id'], i['UserData']['IsFavorite']) print('/Artists/{name} API ', rr.json()['Name'], rr.json()['Id'], rr.json()['UserData']['IsFavorite']) ``` ### What is the current _bug_ behavior? Which when run gives the following output: ``` /Artists API Black Stone Cherry 3ed6477b4add85d52e31485e35d1ab31 False /Artists/{name} API Black Stone Cherry 3ed6477b4add85d52e31485e35d1ab31 True /Artists API Eminem 1c8e6bc10a9064a12ab5f3e3986af2af False /Artists/{name} API Eminem 1c8e6bc10a9064a12ab5f3e3986af2af True /Artists API Five Finger Death Punch 4c3a0bb618c40493877c6da591d709da False /Artists/{name} API Five Finger Death Punch 4c3a0bb618c40493877c6da591d709da True /Artists API P!nk d187ccf894e90c485bccfe25eacd11a0 False /Artists/{name} API P!nk d187ccf894e90c485bccfe25eacd11a0 True /Artists API The Pretty Reckless d537cb7ea6f9831c2ab43ce94e599c0d False /Artists/{name} API The Pretty Reckless d537cb7ea6f9831c2ab43ce94e599c0d True ``` As you can see depending on the method used to pull the data you get a different values for `IsFavorite` from the `UserData` field. ### What is the expected _correct_ behavior? The `\Artists` and `\Artists\AlbumArtists` API end points should both return the same `UserData` and `IsFavorite` values as the `\Artists\{name}` API end point. ### Jellyfin Server version 10.11.6 ### Specify commit id _No response_ ### Specify unstable release number _No response_ ### Specify version number _No response_ ### Specify the build version 10.11.6 ### Environment ```markdown - OS: Arch Linux - Linux Kernel: 6.18.8-zen2-1-zen - Virtualization: Docker - CPU Model: Intel(R) Core(TM) i3-7100T - GPU Model: Intel Kabylake (Gen9) - Plugins: - Artwork - AudioDB - Cover Art Archive - Discogs - DLNA - Fanart - IMVdb - Intro Skipper - LDAP-Auth - LrcLib Lyrics - MusicBrainz - MusicTags - OMDb - Open SubTitles - Playback Reporting - Reports - SmartLists - Studio Images - Subtitle Extract - TheTVDB - TMDb - TMDb Box Sets - TVmaze - Reverse Proxy: Synology DSM - Networking: Host - Jellyfin Data Storage & Filesystem: NVME SSD - Media Storage & Filesystem: NFS & NVME SSD ``` ### Jellyfin logs ```shell Nothing related to API access in logs. ``` ### FFmpeg logs ```shell ``` ### Client / Browser logs _No response_ ### Relevant screenshots or videos _No response_ ### Additional information _No response_
