Object from AI Cast on animnotify

Hello there! I have a little problem trying to cast a monsterBP in my animnotify event, because my monsterbp will be an AI, so when I cast the monsterBP I need an object to connect with the cast!

PS: I already finished my characterBP animnotify without problems, AnimNotify → Cast CharacterBP (object → getplayercontroller index 0).

I tried almost everything in engine on my monsterBP Object, but does not work! Someone can help me please?

Thank you!
