Laravel - Session store not set on request

I recently created a new Laravel project and was following along the guide on Authentication. When I visit either my login or register route, I get the following error:

ErrorException in Request.php line 775:
Session store not set on request. (View: C:\Users\Matthew\Documents\test\resources\views\auth\register.blade.php)

I haven't edited any core Laravel files, I've only created the views and added the routes to my routes.php file

// Authentication routes
Route::get('auth/login', ['uses' => 'Auth\AuthController@getLogin', 'as' => 'login']);
Route::post('auth/login', ['uses' => 'Auth\AuthController@postLogin', 'as' => 'login']);
Route::get('auth/logout', ['uses' => 'Auth\AuthController@getLogout', 'as' => 'logout']);

// Registration routes
Route::get('auth/register', ['uses' => 'Auth\AuthController@getRegister', 'as' => 'register']);
Route::post('auth/register', ['uses' => 'Auth\AuthController@postRegister', 'as' => 'login']);

I don't have much experience with Laravel, so please excuse my ignorance. I'm aware that there is another question asking this same thing, but neither of the answers seem to work for me. Thanks for reading!

Edit:

Here's my register.blade.php as requested.

@extends('partials.main')

@section('title', 'Test | Register')

@section('content')
    <form method="POST" action="/auth/register">
        {!! csrf_field() !!}
        <div class="ui input">
          <input type="text" name="name" value="{{ old('name') }}" placeholder="Username">
        </div>
        <div class="ui input">
          <input type="email" name="email" value="{{ old('email') }}" placeholder="Email">
        </div>
        <div class="ui input">
          <input type="password" name="password" placeholder="Password">
        </div>
        <div class="ui input">
          <input type="password" name="password_confirmation"placeholder="Confirm Password">
        </div>
        <div>
            <button class="ui primary button" type="submit">Register</button>
        </div>
    </form>
@endsection

Solution 1:

You'll need to use the web middleware if you need session state, CSRF protection, and more.

Route::group(['middleware' => ['web']], function () {
    // your routes here
});

Solution 2:

If adding your routes inside the web middleware doesn't work for any reason then try adding this to $middleware into Kernel.php

protected $middleware = [
        //...
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
];

Solution 3:

In my case (using Laravel 5.3) adding only the following 2 middleware allowed me to access session data in my API routes:

• \App\Http\Middleware\EncryptCookies::class
• \Illuminate\Session\Middleware\StartSession::class

Whole declaration ($middlewareGroups in Kernel.php):

'api' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Session\Middleware\StartSession::class,
            'throttle:60,1',
            'bindings',
        ],

Solution 4:

If Cas Bloem's answer does not apply (i.e. you've definitely got the web middleware on the applicable route), you might want to check the order of middlewares in your HTTP Kernel.

The default order in Kernel.php is this:

$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,
    ],
];

Note that VerifyCsrfToken comes after StartSession. If you've got these in a different order, the dependency between them can also lead to the Session store not set on request. exception.
