No value will be returned by reference?

So I’ve run into this issue when following the Setting Up Advanced AI stream with Ian Shadden and Meiszko Zielinski. In the tutorial they use the “On Perception Updated (AI Perception)” node and then drag out the Updated Actors array and run a For Each Loop from the array. Not sure how I could turn the On Perception Updated node into a custom structure.
Any chance this is going to be fixed soon?
