Laravel验证 - helpers.php第466行中的ErrorException：htmlentities（）期望参数1为字符串，给定对象

Question

所以，我按照laravel文档创建了一个验证器。但每次验证失败时，我都会在helpers.php第466行中遇到一个令人讨厌的“ErrorException”。 如果我在重定向之前转储$ validator，一切似乎都很完美，所有错误都存在。但是，在重定向之后，我遇到了问题。

routes.php文件

Route::group(['as' => 'todas'], function(){
  Route::group(['middleware' => ['web'], 'as' => 'web', 'namespace' => 'Web'], function(){
    Route::group(['middleware' => ['auth'], 'prefix' => 'dashboard', 'as' => 'privadas', 'namespace' => 'Privadas'], function(){
      Route::get('criar', ['uses' => 'PrivateController@criar', 'as' => 'criar']);
      Route::post('salvar', ['uses' => 'FestaController@salvar', 'as' => 'salvar']);
    });
  });
});

kernel.php

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],
    'api' => [
        'throttle:60,1',
    ],
];
protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
];

控制器

namespace App\Http\Controllers\Web\Privadas;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Validator;

class FestaController extends Controller
{
    public function salvar(Request $request){
      $validator = Validator::make($request->all(),[
        'numConvidados' => 'required|numeric|min:1',
        'inicioFesta'   => 'required|date|before:' . $request->fimFesta,
        'fimFesta'      => 'required|date|after:' . $request->inicioFesta . '|mais_x_dias:' . $request->inicioFesta . ',1'
      ]);
      if ($validator->fails()){
        return redirect('dashboard/criar')
          ->withErrors($validator)
          ->withInput();
      }
      dd('success');
    }
}

视图中包含$ errors变量

的部分

@section('subHeader')
@if (count($errors) > 0) {{-- Div de erros --}}
  <div class="alert alert-danger">
    {{$errors}}
    <strong>{{ trans('mensagens.opa-algo-deu-errado')}}</strong>
    <br>
    <ul>
      @foreach ($errors->all() as $error)
        <li>{{ $error }}</li>
      @endforeach
    </ul>
  </div>
@endif
@endsection
