Gameplay Ability System (GAS) GaneplayAbilityTargetActor Problem

I try to use class GaneplayAbilityTargetActor_Trace in my GA_Test (Ability) but every time call ability engine crash. I try to find reason why this happends and I find the Make Gameplay Ability Targeting Location info returns null even before data was valid.


The GameplayTargetActor class is abstracto class must be override in c++ to work contains pure function. Why engine is crash every time I try execiute this code.
