I have been periodically receiving the following error message when attempting to sync my library to trakt.tv:

 

Value cannot be null

Parameter name: instance

 

I am running MediaBrowser-Server 3.0.5233.40306 on Windows Server 2008R2.  This has occurred in the past 2-3 server releases and the task will succeed for a while, but once it starts failing the only thing that fixes it is restarting the server service.

 

The following is the relevant snippet out of the log file when the task fails.

I don't know the answer, but I have the same problem from time to time. When it happens, if I happen to look at the upcomming episodes tab in the web client it also give an error about something to do will null (I don't remember it exactly). If I restart the server everything goes back to nornal.

I'll look in to it. It's being caused by movies in trakt locations that are missing either an imdb or tmdb or tvdb id.

If it helps any, I just had this happen again and this is the part of the log when I go to the Upcoming Episodes tab in the web client:

the Trak.tv errors were the same as posted above.

That one isn't related to trakt. It's something with server and your library.

@@Redshirt, I'll keep an eye on it. I've only ever seen it do that when I have the Trakt error in Notifications. Is it possible the error I'm seeing is causing the Trakt problem? Either way, I updated the Trakt plugin and will see if I still get the other problem. Thanks for the speedy fix and keep up the good work, you guys are moving at an incredible pace with the advancement of MB3.

Can't say for certain. I'd just watch it and see what happens for now.

I'll add a check for the next update, but looking at the error, I suspect you have media that has been identified as an Episode, but doesn't have a series attached to it. I'd have a look through the dashboard editor and see if there's anything weird.

Not to hijack this thread but I figured since this issue already exists here it would be best not to create a new thread on it.

 

@@Redshirt, I am noticing the same error on my install.  The other day I saw it and uninstalled/reinstalled the trakt plugin which got it working for a couple days but today its doing it again.  The log message looks the same as @@kfonda posted (mine is included below).  Is there an additional debug logging capability or a way to find out if it is a specific piece of media causing this?
