Cannot avoid "Error Accessed None 'CallFunc_GetController_ReturnValue' from node"

[Gono_1 (GornelBah)]

To be specific, I always get this pair of errors:

Error Accessed None 'CallFunc_GetController_ReturnValue' from node Set MostRecentBomb in blueprint Player_Pawn
Error Accessed None 'CallFunc_CastToPlayerController_ReturnValue' from node Set MostRecentBomb in blueprint Player_Pawn

I’m at my wits end trying to fix these, and have gotten them in multiple parts of my project. It’s always the same error except with a different node name. They only appear when either there is another player or I spawn and possess a new pawn. And here’s the kicker: Everything works perfectly fine. If I stick a print node for the controller name right before or after the spawn, it even prints the name. I’ll post the blueprints I was fiddling with trying to fix the problem, but if anyone knows why this is happening it would be awesome to share.

I’m having this issue on a blueprint that wasn’t previously having any issues and it is driving me MAD. I keep trying to track it down and it moves to a new node that isn’t even trying to grab a player controller.

Same problem. In my case it only appears when the game is in a multiplayer session, though.

Have you tried to use some “IsValid” nodes where it tells you it breaks?

…the error messages are… not good to say it diplomatic. Trying around there a bit could help
