Plex->Jellyfin sync does not work proper. Plex watched movies are shown as "continue watching" in Jellyfin?

[gitttt54]

Hi, (I use docker container v1.0.1 in unraid)

I have ws running a few months now. I did nothing special, only set up 2 backends Plex -> Jellyfin.
I only want to export Plex watchedstate to Jellyfin.
The setup works, BUT (and this is a BIG BUT), almost all the movies/episodes I watched on Plex are under "Continue watching" in Jellyfin. I don't know why and how this happens. Ws is not syncing correctly.

Say, I watched 10 Movies and 10 episodes in Plex the last week, then all of those movies/episodes have different continue-at-times in Jellyfin (maybe when I paused the movie/episode in plex?). None is marked as Watched completely. 8 from 10 movies/episodes show up under "Continue watching" in jellyfin, which is kinda cumbersome and renders the fine tool very useless.

It was this way from the beginning I sucsessfully synced the first time, but I hoped, it would be fixed, which obviously did not happen :-) so i write now here.

Am I the only one expericencing this odd behaviour?
What can I do to fix that problem and have a real sync so jellyfin shows the same watched-state as plex?

Thank you all!

Hello,

its indeed known problem with jellyfin API we in-fact do have a mitigation in place to try to fix it.

https://github.com/arabcoders/watchstate/blob/master/src/Backends/Jellyfin/Action/Push.php#L292C7-L317C12

However i think i have only implemented it aa fix for webhooks.

Can you confirm if you are noticing this via webhooks requests or via export task?

If you want to activate webhooks on both sides you would have to added it to jellyfin too. I suspect the issue as discussed jellyfin doesn't reset PlaybackPositionTicks when item is marked as played via API and retain the position and have to manually reset it to 0 which we do via webhooks. we may have to add it to export as well if not already. We only do it if the item isn't already marked as watched

I have added a webhook in both, jellyfin and plex.
I will come back in a week or two, when I see if it is maybe fixed in ws v1.0.2

At least, for my one-way-sync (plex->jellyfin) setup, I can just delete the database for jellyfin and hopefully plex will overwrite everything within the next days.

Thank you!

I assume as there is no update since then, the issue has been fixed.

Yeah, sorry for the delay, I had trouble with a jellyfin update which killed my database, so I could not check, because I had to revert to 10.10.7.
Now I'm getting a lot of log-messages like:
[17:30:02] webhook.INFO: [G] Request from 'myplexserver' didn't match any user/backend.
And I don't know how to fix it.
I removed all backends, set them up again, added new webhooks in plex/jellyfin, but I can't get rid of that log-message and no watched content is added to jellyfin.
Although no half-watched movies/series are showing up anymore either. So a partial success. ;-D

[17:30:02] webhook.INFO: [G] Request from 'myplexserver' didn't match any user/backend.

You could enable webhook logging to see what he server is actually sending and compare that with your data, you may have users that aren't mapped into watchstate.
