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.

Note: This ONLY happens with TV Enabled. I also tried keeping only the first "skip unwatched import from Trakt" checked and unchecked the rest. Again, it only succeeds on Movies sources.

Spoiler
