AI Tutorial (Ai is not moving agrocheck) cast to ai controller

I went through the tutorial on how to set up the AI several times now and I can’t seem to get it working. The AI just stands there. The only issue I see is that there is a not on the Agrocheck cast to ai function. It says info: The execution path doesn’t end with a return nod. cast failed. I’m not sure what else could cause it. I would upload the blueprints but there is no point I have gone over them a thousand times and they are exactly like they are shown in the tutorial. Has anyone gone through this and had the same issue or can anyone offer some advice I would greatly appreciate it.

Here is the tutorial https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/1/index.html

Sorry it is not in the agro check that has the problem is the close enough blueprint.
