Are you sure the usage of $this->validationFailed() targeting InnoFlash\LaraStart\Services\AuthService::validationFailed() seems to always return null.

        return [

The method factory() does not exist on Illuminate\Contracts\Auth\Guard. It seems like you code against a sub-type of said class. However, the method does not exist in Illuminate\Auth\TokenGuard or Illuminate\Contracts\Auth\StatefulGuard. Are you sure you never get one of those?
