The door wont come down in Level Polish Crypt Raider

I think It has to do with a Blueprint error, But I don’t know how to fix it, The door wont come down if I take the statue

I’m not sure what the issue is but make sure the wall has the mover component as well as making sure its moveable.In the blueprint view port on the mover component on the move offset, set the xyz 0, 0, -600.0
and make sure the trigger box Is set to moveable.

This says that whatever you’re calling GetComponentByClass on is returning nullptr (“None” in blueprint terms). i.e. it doesn’t have a component of the class you’re trying to get.

I have fixed It! Although its inverted and when I pick it up the gate lifts up, I checked my code and everything seems right? is there a problem?
