How can I fix this "accessed none trying to read property" error?

I dont know whats going wrong because it allready runned perfactly. Also my “InventoryRef” is sat to editable and expose on spawn. I think the engine cant call this function because when i put a string infront of this funktion it will printed but in the function it wont. Thx for help.

What exactly do you mean? Its triggered by actor begin overlapping but it dont call the function “AddItem”

oooh wow i found the issu i forgot to connect the ref variable gg

It’s because the inventory in your character isn’t initialised.
