Session store not set on request when accessing 404 page after laravel upgrade

Hi! Does this route use web group middleware? Because in Laravel 5.3 session state, CSRF protection, etc is included in web middleware group. Check it here https://laravel.com/docs/5.3/middleware#middleware-groups

Can you post a code sample where are you using sessions? I think you are using sessions in __construct() method

Has the same problem. Does anybody know the solution? I just can add that for me this problem is connected with the url for non-existing files. And also the exception is throwed, only if the blade contain helper functions like "old('key')".

To avoid problems when you have other exception or recive request with api middleware,change the render function In App/Exceptions/Handler.php to :

public function render ($request, Exception $exception)
{
    if ($this->isHttpException($exception)) {
        switch ($exception->getStatusCode()) {
            case '404':
                \Route::any(request()->path(), function () use ($exception, $request) {
                    return parent::render($request, $exception);
                })->middleware('web');
                return app()->make(Kernel::class)->handle($request);
                break;
            default:
                return $this->renderHttpException($exception);
                break;
        }
    } else {

        return parent::render($request, $exception);
    }
}
