[XanderStrike]

Looking at the logs on the hosted instance this seems related to the Plex TV Agent, I don't have bandwidth to dig into it right now, but it might be helpful if you could share what episode of what show is causing the error? Also does it consistently happen with one episode and not another?

@CorentinB no pressure at all but have you seen any of these errors since implementing support for the new agent?

[nserrano10]

Ran a test with the episodes i got that error from and now it worked. I had just recently upgraded to the new agent so maybe it was still refreshing all the metadata. I will keep an eye and report back if i see this issue again.

Another question: If i marked on plex an episode as watched, will it mark it on trakt?

[XanderStrike]

Interesting yeah it could be that it didn't have the IDs populated yet.

Unfortunately Plex doesn't send us anything when you check off an episode, so no Trakt won't find out about it. We just get play, pause, and stop events.

Ran some more tests and yesterday got the error with American Idol S19 E19 and Restaurant Impossible S19 E1

Any updates on this issue? I'm also noticing the same error on certain episodes.

[ColinHebert]

FWIW, this happens when the search on trakt (using https://api.trakt.tv/search/%s/%s?type=episode) doesn't return any results. This can happen if the episode's TVDB ID isn't found on trakt.
Trakt uses TMDB as the source of truth, so if the episode in question in TMDB doesn't have a reference to the TVDB episode ID; it will fail:

This could be fixed with doing lookups with different sources when one fails (not just TVDB iD, but TMDB ID, etc.).
Preferably https://github.com/XanderStrike/goplaxt/blob/master/lib/trakt/main.go#L114-L116 would also check wether the reply is not empty.
