Trying to get reference from blueprint class but it always comes up not valid

**Conversation2dController reference It is always not valid. I have this code set up in my NPC pawn blueprint. The Event on interaction requested is attached to my world character or (player character). So when my character gets within range of this NPC this code will activate when I press the “E” key. So pretty much the problem is that the conversation2dcontroller is always not valid. I’m just unsure as to why though. Hmm…

What I’m trying to do is activate my dialogue code. But the blueprint reference “conversation2dcontroller” that is associated with it is always not valid.

Any help would be much appreciated.**
