Casting to Character Controller Always Failing

So I’m following this (How To Make An Animation Blueprint And Blendspace | In-Depth Explanation - Unreal Engine 4 Tutorial - YouTube) tutorial and I tried to cast to my character controller but it always fails. I’ve tried to use “try to get pawn owner”, “get player character”, and "get player controller and they always fail. What should I put in for object?

First of all, you need to share the code, nobody wants to watch a tutorial and guesses where you did a mistake.

Ok, I see. Haven’t worked with animation and I am not sure about does it have the right owner or not. But in this case, if it has you need to try “get owner”.
And also, you can use the blueprint interface to send the player pawn ref to the animation blueprint.
