Laravel validator throws an exception instead of redirecting back

Question

After I upgraded to Laravel 5.2 I encountered a problem with the laravel validator. When I want to validate data in a controller take for example this code.

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class ContactController extends Controller
{
    public function storeContactRequest(Request $request)
    {
        $this->validate($request, [
            '_token' => 'required',
            'firstname' => 'required|string'
            'lastname' => 'required|string'
            'age' => 'required|integer',
            'message' => 'required|string'
        ]);

        // Here to store the message.
    }
}

But somehow when I enter unvalid data it will not redirect me back to the previous page and flash some messages to the session but it will trigger an exception and gives me a 500 error page back.

This is the exception I get. I have read in the documentation that the ValidationException is new instead of the HttpResponseException but I don't know if it has anything to do with this.

[2016-01-05 11:49:49] production.ERROR: exception 'Illuminate\Foundation\Validation\ValidationException' with message 'The given data failed to pass validation.' in /home/vagrant/Code/twentyre-webshop/vendor/laravel/framework/src/Illuminate/Foundation/Validation/ValidatesRequests.php:70

And when I use a seperate request class it will just redirect back with the error messages. It seems to me only the validate method used in a controller is affected by this behaviour.

Update your App\Exceptions\Handler class

use Illuminate\Auth\Access\AuthorizationException;
use Illuminate\Database\Eloquent\ModelNotFoundException;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Illuminate\Foundation\Validation\ValidationException;

/**
 * A list of the exception types that should not be reported.
 *
 * @var array
 */
protected $dontReport = [
    AuthorizationException::class,
    HttpException::class,
    ModelNotFoundException::class,
    ValidationException::class,
];

I also recommend you to read the docs how to migrate to laravel 5.2, because there were some breaking changes. For example this, ValidatesRequests trait throws Illuminate\Foundation\Validation\ValidationException instead of Illuminate\Http\Exception\HttpResponseException
