GetCorrespondingObjectFromSource error but no mention in solution

I'm getting a

Code (CSharp):

1.     MissingMethodException: Method not found: 'UnityEditor.PrefabUtility.GetCorrespondingObjectFromSource'.

error, but a solution wide search doesn't produce anything calling GetCorrespondingObjectFromSource so I can't figure out how to track it down? This is 2018.3.9f1 and it happens in a blank scene soon as soon as I hit play. I just upgraded from 2018.2 but can't figure out how to find the problem.

The full error is:

it was in a dll i was able to update which fixed the error

 

I have the exact same issue. Can you share which DLL was the issue and how you replaced it?

 

I use Mirror which until recently was packaged in a dll. After upgrading it to the latest which is now individual cs files, I was able to see the issue and correct it. If a solution wide search in visual studio doesn't give you any results I'd suggest you do a search for any dlls in your project, figure out who they belong to, and try to update them.

 

• Changed reference to PrefabUtility.GetPrefabParent() to PrefabUtility.GetCorrespondingObjectFromSource() to reflect public API change in 2018.2

Unity provides automatic API update for upgrading but not downgrading.

Change GetCorrespondingObjectFromSource to GetPrefabParent by yourself.
