Laravel Session Middleware broken
<p>On my local system everything works fine, but after deploying Laravel 5.2 on our test system it looks like the session middleware is broken. Can someone help here? </p>

<pre><code>Argument 1 passed to Illuminate\Session\Middleware\    
StartSession::addCookieToResponse() must be an instance of  
Symfony\Component\HttpFoundation\Response, boolean given, called in   
... /httpdocs/service/vendor/laravel/framework/src/Illuminate/Session 
/Middleware/StartSession.php on line 72 and defined
</code></pre>

<p>The global middlewares:</p>

<pre><code>protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    \App\Http\Middleware\CORSMiddleware::class,
    \LucaDegasperi\OAuth2Server\Middleware\OAuthExceptionHandlerMiddleware::class
];
</code></pre>
