Plex Watchlist Sync fails when Plex Discover returns metadata under `MediaContainer.Video` instead of `MediaContainer.Metadata`

[ik8sqi]

Description

Seerr currently assumes:

const metadata = detailedResponse.MediaContainer.Metadata[0];

However, Plex sometimes returns:

<MediaContainer ...>
  <Video ... ratingKey="669748dc85be974cd2ab194c" title="Marty Supreme" type="movie">
    <Guid id="tmdb://1317288"/>
    <Guid id="imdb://tt32916440"/>
    <Guid id="tvdb://358417"/>
  </Video>
</MediaContainer>

This causes Plex Watchlist Sync to fail because MediaContainer.Metadata is undefined.

---

Version

Seerr Stable 3.2.0
Docker image: ghcr.io/seerr-team/seerr:latest

---

Steps to reproduce

1. Add a Plex Watchlist item whose Plex Discover metadata endpoint returns <Video> instead of <Metadata>.
2. Trigger Plex Watchlist Sync.
3. Seerr fails while processing the watchlist item.

Verification command:

curl -sS -H "X-Plex-Token: $PLEX_TOKEN" "https://discover.provider.plex.tv/library/metadata/669748dc85be974cd2ab194c" | grep -oE '<(Metadata|Video)[ >]' | head -1

Output:

<Video

---

Expected behavior

Seerr should handle both response shapes:

detailedResponse.MediaContainer.Metadata?.[0]

and:

detailedResponse.MediaContainer.Video?.[0]

---

Actual behavior

Plex Watchlist Sync fails when MediaContainer.Metadata is missing.

---

Tested local fix

This fixed the issue locally:

const metadata = (
  detailedResponse.MediaContainer.Metadata?.[0] ??
  detailedResponse.MediaContainer.Video?.[0]
);

---

Relevant source line

In /app/dist/api/plextv.js:

const metadata = detailedResponse.MediaContainer.Metadata[0];

Version

3.2.0

Steps to Reproduce

Steps to reproduce:

1. Add Marty Supreme (2025) to the Plex Watchlist.
   

2. Run Plex Watchlist Sync in Seerr 3.2.0.
   

3. The Plex Discover metadata endpoint for that item returns <Video> instead of <Metadata>.
   

4. Seerr fails because it assumes detailedResponse.MediaContainer.Metadata[0] exists.
   

I also saw the same failure pattern with other watchlist items, including Highlander (unreleased yet) and Perfect Days (2023).

While you're right on one point, the discover endpoint returns a Video container for movies, I can't reproduce your issue. Tested with the movie you gave and it worked on my side. Also, from your logs it seems like it's working for other medias.
