This is a Debugging video for how to fix an Unassigned Reference Exception error when using an Observed Component in Unity with Photon. This is a very easy error to fix as It only takes switching one variable in the inspector. If you are receiving this error it is probably because you accidentally made one little mistake without realizing it.
To fix this error all you must do is look at all you Photon Prefabs and make sure that the Observe Option of the Photon View component is set to off or you have at least on observed component set. If the Observe option is turned on and you don’t have a component being observed then you will be receiving this error.
