Why am I getting reference errors?

Why am I getting these errors in my Behavior Tree? I am doing a simple move actor to, and in Play the referenced actor DOES move around, so it seems to be working. What gives?

Can you show the right hand end of the error? ( that’s the crucial part ).

Well the error is saying ControlledPawn is null so I don’t think it matters what the right part of the error says. Probably there’s some AI configuration issue that’s causing this BTTask to not be linked the the AI pawn.
