Happy2Play 8282 Posted August 29, 2015 Share Posted August 29, 2015 (edited) @@ebr Looks to be something with MBPlus plugin. Object reference not set to an instance of an object.

ebr 14913 Posted August 29, 2015 Share Posted August 29, 2015 Hmmm... I think what is going on here is that is an old object that was created against a user that doesn't exist anymore. The thing is, I'm not sure even if we solve that particular error that there won't just be another one right behind it because these objects may not instantiate properly when read straight out of the database like this. Most of them depend on constructor parameters. Luke - can the task just delete the offending object when a serialization error like this occurs and move on? I think MBPlus will be able to recover it. The only reason some of these are saved in the DB at all is because the API requires it to be in order to deliver an image for it. Link to comment Share on other sites More sharing options...
Kent 91 Posted August 29, 2015 Author Share Posted August 29, 2015 I don't use MBPlus anymore and can remove the plugin. But i'll hold off doing anything in case you want me to try a fix. Sounds like an edge case and might not be worth full analysis? Link to comment Share on other sites More sharing options...

ebr 14913 Posted August 30, 2015 Share Posted August 30, 2015 Still failing for me. I think due to the fact that I have old objects in my DB from plug-ins that no longer exist. 2015-08-30 15:45:19.3247 Debug - SqliteItemRepository: Unknown type YoutubePlugin.Entities.YoutubeVideo 2015-08-30 15:45:19.3247 Debug - SqliteItemRepository: Unknown type YoutubePlugin.Entities.YoutubeCollectionFolder 2015-08-30 15:45:19.3247 Error - App: Error *** Error Report *** Version: 3.0.5720.23532 Command line: C:\Users\Eric\AppData\Roaming\MediaBrowser-Server\System\MediaBrowser.ServerApplication.exe Operating system: Microsoft Windows NT 6.1.7601 Service Pack 1 Processor count: 8 64-Bit OS: True 64-Bit Process: False Program data path: C:\Users\Eric\AppData\Roaming\MediaBrowser-Server Application Path: C:\Users\Eric\AppData\Roaming\MediaBrowser-Server\System\MediaBrowser.ServerApplication.exe Value cannot be null.
