Hi @NekoEn,
Given it worked with a cast node, your original reference won’t be a nullptr. You will likely be using an Actor reference or some parent type on which the property you are trying to get doesn’t exist.
You could keep the Alba variable the same and just use the cast node which should work fine. Alternatively you can change the type of Alba to BP_Character (again, it’s probably some kind of parent Character or Actor class currently) so that when you call functions directly from the Alba reference it will have the correct property to use.
Thanks,
Hayden
