How to change my Animation State (in the Animation Blueprint) from the Character blueprint

I’m trying to setup an enemy AI so the character blueprint and animation blueprint I reference here is the enemy blueprint, not the player. In my character blueprint I make the enemy face the player but he floats in the idle animation rather than activating the turn animation. I reference the animationblueprint object in the character blueprint and set the variable in the animation blueprint (the variable that should activate the animation for turning).

When I press play it does not work and when I exit I get this error “Accessed None ‘AnimationBlueprint’ from node Construction Script in blueprint ShockTrooper_characterBlueprint”

What can I do?

Did you figure this out?
