Calculate statistics for all users Failed

[austinchief 3]

At somepoint, I do not know when it started, my daily "Calculate Statistics for all users" started failing.    It runs to 90% then fails.     

Here is the error alert:

Value cannot be null. (Parameter 'key') at System.Collections.Generic.Dictionary`2.FindValue(TKey key) at System.Collections.Generic.Dictionary`2.TryGetValue(TKey key, TValue& value) at Statistics.Helpers.Calculator.CalculateMovieQualityList() at Statistics.ScheduledTasks.CalculateStatsTask.MediaBrowser.Model.Tasks.IScheduledTask.Execute(CancellationToken cancellationToken, IProgress`1 progress) at Emby.Server.Implementations.ScheduledTasks.ScheduledTaskWorker.ExecuteInternal(TaskOptions options)

Interestingly, "Calculate statistics for TV Shows" runs daily with no issues.

Anyone know how to debug this?

Thanks for the quick reply!    Looks like I need to roll back to 3.3.2.1, but where do I source that version?

Have you look in the plugin catalog ?

I just uninstalled and reinstalled.    Dug deeper into that thread and saw the author removed the 3.3.2.2 version, so the 3.3.2.1 version is now the latest to install.    Been awhile since I have installed a plug-in, I see the drop down menu for the different available version.    Thanks again for the quick reply and pointer to the thread I should have found via search!
