I use Symfony 7.0 framework. I got stuck with this for a few days. Googled, used AI chat, read documentation, but nothing helped.

I can’t get use details inside of my Event Listener class from Security component. This code:

<?php

namespace AppEventListener;

use SymfonyComponentEventDispatcherAttributeAsEventListener;
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentHttpKernelEventExceptionEvent;
use SymfonyComponentHttpKernelExceptionNotFoundHttpException;
use SymfonyComponentHttpKernelKernelEvents;
use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyBundleSecurityBundleSecurity;

final class ExceptionListener extends AbstractController
{
    public function __construct( 
        protected Security $security, 
    )
    {
    }

    #[AsEventListener(event: KernelEvents::EXCEPTION)]
    public function onKernelException(ExceptionEvent $event): void
    {
        // Getting exception from ExceptionEvent object
        $exception = $event->getThrowable();

        // Getting current user
        $user = $this->security->getUser();
        die(var_export($user));

        // Provera da li je izuzetak tipa NotFoundHttpException
        if ($exception instanceof NotFoundHttpException) {
            // Odredjivanje template-a u zavisnosti od uloge korisnika
            $template = 'error404_user.html.twig'; // Default template za ulogovane korisnike
            $roles = [];

            // Provera da li je korisnik prijavljen i koje uloge ima
            if ($user) {
                $roles = $user->getRoles();
                if (in_array('ROLE_ADMIN', $roles)) {
                    $template = 'error404_admin.html.twig'; // Template za admina
                }
            }

            // Generisanje odgovora sa odgovarajućim template-om
            $response = new Response();
            $response->setContent(
                $this->render($template, ['exception' => $exception, 'roles' => $roles])->getContent()
            );

            // Postavljanje HTTP status koda na 404
            $response->setStatusCode(Response::HTTP_NOT_FOUND);

            // Postavljanje odgovora u ExceptionEvent objekat
            $event->setResponse($response);
        }
    }
}

This is service.yaml code:

# This file is the entry point to configure your own services.
# Files in the packages/ subdirectory configure your dependencies.

# Put parameters here that don't need to change on each machine where the app is deployed
# https://symfony.com/doc/current/best_practices.html#use-parameters-for-application-configuration
parameters:

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

    AppEventListenerExceptionListener:
        tags: [kernel.event_listener]

    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App:
        resource: '../src/'
        exclude:
            - '../src/DependencyInjection/'
            - '../src/Entity/'
            - '../src/Kernel.php'

    # add more service definitions when explicit configuration is needed
    # please note that last definitions always *replace* previous ones

die(var_export($user)); always backs NULL.

I want to get user details inside of event listener. Depending of user role, the user should be redirected to an appropriate page. Can someone help me with this?
