Watchlist sync creates requests for seasons that don't exist

[tippmar]

Description

I enabled watchlist sync recently and noticed an issue when one of my users enabled it for their account.

A request was created for Season 3 of a show that has been on Seerr for several months and is in the middle of it's second season -- there is no Season 3 and no way in Seerr to request Season 3 for that show.

If I delete the Season 3 request, it just comes back the next time watchlist sync runs (and sends another auto-approved email to the user).

This is not limited to a single show either - I'm seeing at least 3 instances of this behavior, from the same user's watchlist.

I've re-run Plex library full scan, watchlist sync and Sonarr sync in Seerr, nothing changed.

I don't see any issues in the logs related to the show in question, just the usual "updating existing title" and "guids are cached, skipping metadata request".

Version

Stable 3.1.0

Steps to Reproduce

I'm not entirely sure how to repro.
The user had the show on their Plex watchlist prior to me enabling the feature in Seerr and prior to them enabling it for their account.

The show in question was already in Seerr via a manual add a few months ago - the show was not originally added by a user request.

The request for the non-existing season appeared as soon as the user enabled watchlist sync for their account.

You need to share what metadata provider you have series set to.

In settings > metadata.

I was using TMDB; switched it to TVDB, re-scanned and didn't see any change. I deleted the request but it came right back on the next watchlist sync.

Check the series on plex. So you can see what metadata provider its using and why it has a season 3 since s3 request came from Plex watchlist meaning plex discover showed that series having a season 3. Its coming from plex so need to see why it has a season 3.

Plex is using the default (built-in) metadata providers ("Plex Series" for my TV library), which I guess pulls from multiple sources and does some kind of magic on the results.

But TMDB for the series in question shows a season 3 with zero episodes. So if that's part of the data Plex is getting, I suppose that explains the source of the problem.

In any case, if I already have a series in Sonarr and it's going to monitor for new seasons, there's no reason for Seerr to honor a "rogue" season request from the watchlist -- the request has exactly zero impact on what's already going to happen when that season finally drops.

And, while unrelated (and possibly the subject of other issues; I didn't search yet) - if I delete a request from Seerr, it's really annoying to have it come back a few seconds later when the watchlist sync runs again.

That is unrelated. And not a bug. Quite literally what watchlist sync is designed for. You'll need to remove the item from watchlist. (Or decline requests, which shouldn't sync declined ones though there currently is a bug that might bypass this which we need investigating). But deleting requests and watchlist syncing is normal if you are just deleting and not declining or not removing it.

Reopening because this is still a relevant bug report. We should validate requested seasons via tmdb even if its a season that exists in plex's source.
