Blueprint Interface function not firing

I have character controller blueprint which should trigger different animations in animation blueprint using a blueprint interface. However, the animation blueprint doesn’t fire the Event Climbing Ledge. Both the character controller blueprint and animation blueprint have the interface implemented in the class settings.

I have tried using just the Get Anim Instance return value (without casting) but that neither worked. I have checked that the Cast To Player_Anim_Blueprint is successful.

did you find solution?

Ok, I found it.

from Skeletal Mesh node Get Anim Instance and from this cast to interface directly, and from As Anim Interface need to call his function.
