Multiplayer error message but everything works????

I call a sit function on a multiplayer game. The goal is to restrain the camera view for the player that wanted to sit. It WORKS the client or the server is restrained and the other is not. This is not called with run on server or multicast (everything else is but I figured I did not need to in this case) Pic 1 is the nodes When called on client there is no problems. When called on the SERVER everything works, but i get an error and I get sad Pics 2 and 3 is the error message I get, only when server tries to sit
