Trakt plugin Scheduled Task fails

[noybman 10]

I'll start by saying I only started using Trakt a few months ago at most. But the good news in that regards is that it worked!

Now the bad news.... it no longer works! (whats annoying is that even with TRACE logging turned on it does not give any detail.) however, I've been able to narrow it down...

The issue is related to TV scan. If I only include Movies, it completes successfully. However, with TV enabled, it fails. It doesn't give any useful info like a specific show it is failing on. I have two different TV folders that are in my library and it crashes the exact same way for either one of them.

Hi, please try the 3.8.2 update to the trakt plugin and let us know if this error is resolved now. Thanks.

No more immediate crash, but I believe it is fair to say the query/match being used is a swing and a miss but only for TV. Movies looks good. So here is a log snippet with debug tuned on that shows the Movies working, and the TV not.

Just to be clear, it does not work for a single TV show, not one.

 

But progress.... no crash. The task completed

[Luke 42723]

HI there, can you please provide a specific example?

How to Report a Problem

Thanks !

 

[noybman 10]

I provide the exact dump of hundreds of exampes, via the trace of the log file. Its literally in my "spoiler" tag.

[Luke 42723]

OK can you please pick one and provide some discussion about it? What exactly makes you think it didn't sync?

[noybman 10]

I kinda feel like you are trolling me?

And in fact, it is not marked as watched on Emby, but in Kodi and on Trakt it is.

The Bear... same thing. The list goes on, for EVERY single TV show I have. Not just one here or there, but EVERY SINGLE ONE. The log says the same thing seen above for ALL of them.

 

But the point I would think the log made clear, is that it says it cannot match ANY show. The log says this. But because you asked, I checked Kodi... watched history is all good. Look at my account on Trakt, watch history is all good. Run the Task scan on Emby again, with the plugin Trakt 3.8.3.0, and it does not work for TV but does work for Movies.

This agrees with the log, that I posted.

Are you telling me when you run this version of the plugin, it works for you? I would think the result the same. My folders aren't crazy names. The example I posted doenst look strange.

"T:\TV\American.Ninja.Warrior.(2009).[tvdb-212411]\Season.05\American.Ninja.Warrior.-.S05E12.-.Baltimore.Finals.(2).SDTV.mp4"

It Syncs for me. I uninstalled the plugin, and then reinstalled again, then grabbed the code from trakt, and pasted it into the Emby plugin. Clicked save and it saved. It's back !!!

[noybman 10]

I have re-sync'd the code (AI suggested I do that), but that was before the new version they made for the fix on my initial report. I did not uninstall and reinstall the plugin completely. I dont love that if I had a lot of users using it, but I am the only one. I will go try that now.

How have you configured the trakt options?

[noybman 10]

A full log for your pleasure.

I did a plugin uninstall, restarted, then a fresh key, then the scheduled task. While it reports it was successful, the log still indicates no matches for a single TV show. But Movies matched fine.

I shared my trakt options above. They remain as pictured.
