Symfony2 SecurityController error

Question

I'm new in symfony and I'm following the login form tutorial(https://symfony.com/doc/2.8/cookbook/security/form_login_setup.html) but I get the following error:

Uncaught PHP Exception LogicException: "The controller must return a response (null given). Did you forget to add a return statement somewhere in your controller?" at /var/www/html/app/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/HttpKernel.php line 157
Context: { "exception": "Object(LogicException)" }

I use the same SecurityController:

class SecurityController extends Controller{


 * @Route("/admin", name="login")

public function loginAction(Request $request)
{

 $authenticationUtils = $this->get('security.authentication_utils');

// get the login error if there is one
$error = $authenticationUtils->getLastAuthenticationError();

// last username entered by the user
$lastUsername = $authenticationUtils->getLastUsername();

return $this->render(
    'security/login.html.twig',
    array(
        // last username entered by the user
        'last_username' => $lastUsername,
        'error'         => $error,
    )
);
}

/**
 * @Route("/login_check", name="login_check")
 */
public function loginCheckAction()
{
    // this controller will not be executed,
    // as the route is handled by the Security system
}

security.yml

What does your security config look like? (app/config/security.yml) — Wouter J

In your security.yml, try to replace

check_path: login_check

by

check_path: /login_check

And make your method like this :

/**
 * @Route("/login_check", name="login_check")
 */
public function loginCheckAction()
{
    throw new \RuntimeException('You must configure the check path to be handled by the firewall using form_login in your security firewall configuration.');
}
