Unity - InputSystem error : "Cannot generate reader for abstract class InputControl"

Question

I have been using the new Unity Input System with good success until I got this error and I don't know how to solve it. The first error reads "(0,0): error Cannot generate writer for abstract class InputControl". Console

I am using Input System 1.3.0. I also use the networking asset Mirror in case it has something to do with it.

Can someone help me here? =)

Answer 1

Ok I found the problem:

I added the [Command] header over one of my Input Handler method, after removing it it works fine.

    //[Command]
public void OnScroll(InputAction.CallbackContext ctx)

not

    [Command]
public void OnScroll(InputAction.CallbackContext ctx)
