Error with base Third Person Project variable: Accessed None trying to read Follow Camera

I’ve been trying to follow on a tutorial which focus on making a pick up items system, and I’ve been following it step by step. However, for some reason there’s an error with my “Follow Camera” variable. I know it means that my variable isn’t correctly tied to it’s reference object, but what I’m not getting is that this variable is one already made by the base Third Person Project you can open in Unreal, so it was supposed to be correctly tied to tha camera itself. How can this variable not be valid? I can’t seem to find where this invalidation comes from, and haven’t changed the Third Person Blueprint in any way or form besides only tweaking it to add a different character model.

Here’s the problematic blueprint for reference:

The BP_Items referenced is just a simple blueprint to spawn items from a list, which is working correctly.
