Laravel 5.3 получить попытку верно, но Auth :: User вернуть ноль?

Как сказано в названии, в VendorController postLogin метод dd(Auth::user()) получить значение NULL, но $attempt получить результат trueЯ не могу получить данные, которые были попытки.

мой routes/web.php

Route::group(['prefix' => 'vendor','as' => 'Vendor.'], function () {
Route::get('login', 'VendorController@login')->name('Login');
Route::post('login', 'VendorController@postLogin')->name('Post.Login');
});

мой VendorController:

  public function postLogin(Request $request)
{
$attempt = Auth::guard('vendor')->attempt([
'acctId'   => $request->acctId,
'password' => $request->password
]);

if($attempt){
dd(Auth::user());
}
}

мой Vendor модель

namespace ACME\Entities;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Auth\Authenticatable as AuthenticableTrait;
class Vendor extends Model implements Authenticatable
{
use AuthenticableTrait;

protected $table = 'vendor';
protected $primaryKey = 'id';
public $timestamps = true;
protected $fillable = [
'acctId',
'password',
'active',
'remark'
];
protected $guarded = ['password'];
}

мой config/auth.php

return [

'defaults' => [
// 'guard' => 'web',
// 'passwords' => 'users',
'guard' => 'user',
'passwords' => 'users',
],

'guards' => [
