        Pjax::respond($response);

It seems like $response can also be of type Illuminate\Contracts\Routing\ResponseFactory; however, parameter $response of Yeelight\Http\Middleware\Pjax::respond() does only seem to accept Symfony\Component\HttpFoundation\Response, maybe add an additional type check?
