Symfony/Monolog: Custom processor with FOSUserBundle data

Question

I'd like to add the userId and username , provided by FOSUserBundle , to my Logger (Monolog). I followed this tutorial to be able to log the IP, it's working.

My code below breaks, because $this->tokenStorage->getToken() is NULL , even if I'm logged in.

services.yml

monolog.processor.user:
    class: AppBundle\Log\UserProcessor
    arguments: [ "@request_stack", "@security.token_storage" ]
    tags:
      - { name: monolog.processor }

AppBundle/Log/UserProcessor.php

use Symfony\Component\HttpFoundation\RequestStack;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use AppBundle\Entity\User;

class UserProcessor
{
    private $requestStack;
    private $tokenStorage;

    public function __construct(RequestStack $requestStack, TokenStorageInterface $tokenStorage)
    {
        $this->requestStack = $requestStack;
        $this->tokenStorage = $tokenStorage;
    }

    public function __invoke(array $record)
    {
        $username = '';
        $userId   = 0;
        $user     = $this->tokenStorage->getToken()->getUser();

        // !!! ERROR !!!
        // $this->tokenStorage->getToken() is NULL

        if ($user instanceof User) {
            $username = $user->getUsername();
            $userId   = $user->getId();
        }

        $record['extra']['user_id']  = $userId;
        $record['extra']['username'] = $username;

        return $record;
    }
}

Any ideas? Thanks in advance!

The problem is that the processor is called to log something before security has been able to act and get the current user. Just check if token exists and if it doesn´t don't log user
