Why do I get "Cannot cast value to Object" when calling :InvokeClient on RemoteFunction?

I am trying to call :InvokeClient on a remotefunction, but whenever I try to do it, it gives me the error of "Cannot cast value to Object". I have tried removing the call, and it did not error. I am also sure that the call to the remote function, and have done many tests to prove so. Is there a way I can resolve this issue?
