[Bug]: Error reporting playback progress

[Arubinu]

I've read the documentation

• I'm running the latest version of tubearchivist-jf-plugin.
• I'm running the latest version of TubeArchivist.
• I have read the how to open an issue guide, particularly the bug report section.
• I have searched for both closed and open already existing issues about the problem I am reporting.

Operating System

LXC Dockge (Docker)

Your Bug Report

Describe the bug

The folder names (and probably video names) are not renamed and retain the IDs format.

Steps To Reproduce

Since updating Jellyfin to v10.11.5, the plugin is no longer working; the following errors appear in the logs.

Expected behavior

Name the media correctly to remove the ID.

Relevant Jellyfin log output

Anything else?

Since the Jellyfin update, even my Android app can't communicate with it to retrieve the list of titles in my media library!

[Jurrer]

I can say, plugin works fine on v10.11.5 on my end.
Maybe the plugin did not get updated properly? Did you try reinstalling it?

[Arubinu]

I just did it properly to be sure that wasn't the problem, and here are the resulting errors.:

[fazadaoc]

i'm not sure if it's related to this issue but since updating to jellyfin 10.11.x and installing ta-jf plugin i could not see any event of media play in jelly's activity
i described the issue here jellyfin/jellyfin#15992
i had a constant repeat of this:

despite having the sync deactivated both ways

once i removed the plugin i could see again videoPlayback start/end events

[focustense]

While this issue was obviously caused by an upstream change and isn't really the fault of the plugin, it is nevertheless a nastier bug than the original report implies, because the same or similar hook runs on events like OnWatchedStatusChange in response to actions like MarkPlayed, for all Jellyfin content, not just YouTube/TA videos.

In other words, as long as the TubeArchivistMetadata plugin is installed, it is impossible to perform certain actions in Jellyfin like marking a movie, episode, season or show as watched, or favoriting/un-favoriting. Desktop clients will silently fail to perform their action (with a similar message about the missing Jellyfin.Data.Entities.User in the server log), and Android clients will crash outright.

I can verify by uninstalling the TA plugin, seeing that these actions begin working again, and then reinstalling the TA plugin and observing them break again.

The issue may have been flying under the radar for a while because, for whatever reason, the up next/continue watching features of Jellyfin still seemed to work for at least some content despite certain less-visible aspects failing (see e.g. fazadaoc's comment). It seems that progress reporting is only subtly broken, whereas changing watched status, favorite status, etc. through the UI (i.e. anything that needs to call SaveUserData) is fully broken for all videos.

I don't know if the AI-assisted commit linked above is a proper fix, as refactors that involve moving/renaming types often involve more significant architecture changes, and the author did not even merge it in his own fork... but if it does fix the issue then it would be swell to see it pulled in sometime soon.

[ferrouswheel]

Re: my claude commit. It worked for me locally, but wasn't confident enough in it being the solution to submit a PR here.

As I recall, I believe I found evidence that the plugin lost my settings including auth for tubearchivist, and I also recompiled with the new changes from Claude.

Thus I was unsure if I was actually experiencing the same bug, had lost my settings before/after the bug, or something else. But making sure settings were filled in and recompiling with updated Jellyfin, got things working for me.
