What exactly does it mean, and how do I fix it? "Error Accessed None 'CallFunc_K2_GetPawn_ReturnValue' from node Branch in blueprint MyController"

I’m currently in a 48 hr Game Jam with a team using UE4. I myself am fairly new to the fourth iteration of Unreal, as are two of my teammates. Noone can figure out what this and similar errors mean or how to fix them. Any information and/or solutions to this problem are greatly appreciated.

Controllers dont always have pawns so there are circumstances where youre accessing through a null, you should check to make sure the output from the object pin on Get Pawn is valid and if its not working how it should check to make sure that self is infact passing your Controller.

So is this error is saying that there is a null pointer being passed as an object? can anyone confirm this?

Yes this answer should be correct.
