Laravel Contract提供500错误

I've made a Contract interface and an Eloquent Repository for my application but I'm getting a 500 error when I try to use it.

I have a feeling it has something to do with the way it is registered. To do this with a service provider which has the following register method:

/**
* Register service provider bindings
*/
public function registerBindings() {
    $this->app->bind(
        \App\Repositories\Backend\EventContract::class,
        \App\Repositories\Backend\EloquentEventRepository::class
    );
}

I then use the contract as follows in my controller:

class EventController extends Controller {

/**
 * @var EventContract
 */
protected $events;

/**
 * EventController constructor.
 * @param EventContract $events
 */
public function __construct(EventContract $events)
{
    $this->events = $events;
}

/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{

    return view('backend.events.index')
                ->withEvents($this->events->getEventsPaginated(25, 1));

When I load the page with the 500 error there's no entry in the Laravel logs or the Nginx logs (I use Homestead with Vagrant).

Any idea? Thanks in advance

EDIT: Found some logs!

May be stupid pointers, but no harm checking:

1. Double check the namespace in respective files i.e. EventContract and EloquentEventRepository class files.

2. Check if you have imported the namespace in the EventController if not using full path

3. After registering service provider did you run composer dump-autoload -o

Try using chrome devtools to see the response if debug is on
