this not works…
and i don’t know what “querier actor” exactly… 
AI controller? AI Actor? or just … Context???
The “querier actor” should be the actor that’s controlled by the AIController which contains Blackboard Component and that’s why you can call “GetBlackboard” and use it to get “GetValueAsActor”. From the Blueprint, you are getting a Vector from a BlackboardKey called “Noise Location”. This means it should be set by someone else. You need to tell us more what you are trying to accomplish.
Can you tell us the context of the blueprint you are showing? Can you also write down the return values of “Querier Actor”, “Get AIController” and “Get Blackboard”. Use the print node to figure out what those are.
