ArgumentOutOfRangeException Instantiating PlayerInput

I have set the join behavior for the PlayerInputManager to manual and I am instantiating two PlayerInput instances using the following code:

 PlayerInput playerInput = PlayerInput.Instantiate(prefab, pairWithDevice: Keyboard.current);
 PlayerInput playerInput = PlayerInput.Instantiate(prefab, pairWithDevice: Gamepad.current);

However I keep getting following error for the gamepad one:

 ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

I check the list of InputUsers and PlayerInputs and can see that there are two InputUsers created one for the keyboard and one for the gamepad but there is only one PlayerInput available in the system which is assigned to the keyboard.

Does anyone have any idea what is wrong here?
