My custom character cannot move when i spawn and i get this output message :( why?

Model:GetPrimaryCFrame() failed because no PrimaryPart has been set, or the PrimaryPart no longer exists. Please set Model.PrimaryPart before using this. A primary part should be set so that the character can be spawned correctly Infinite yield possible on 'Workspace.BakingPeanut.Torso:WaitForChild("Right Shoulder")' -- i am trying to make a custom character in my game however, when i try to use the "dummy" head for the rig r6 , i cannot change it's primary part pls tell me why this is happening :(
