Stucked with camera pawn!

Hello everyone, i am sure its a stupid thing but i cant find out why i always get this when i try to move my pawn in the game it doesn’t move and give me this error :frowning:

I’ve asked around and no one seems to find out why it doesn’t work properly.

Thanks !(edited)

Just so everyone know you need to have the same kind of PlayerState and GameMode or PlayerStateBase and GameModeBase. Or you have the problem i had.
