Problem monolog doctrine channel logging, symfony 4, with php

Question

im have problem in monolog doctrine logging (in symfony 5):

framework.yaml:

monolog:
    channels: [doctrine_channel]
    handlers:

        main:
            channels: ["!event", "!doctrine_channel"]
        doctrine:
            type: service
            channels: [doctrine_channel]
            id: app.logger.doctrine_handler

services.yaml:

  app.logger.doctrine_handler:
        class: App\Util\DoctrineHandler
        arguments:
            - "@doctrine.orm.entity_manager"

src/Utils/DoctrineHandler.php:

<?

namespace App\Util;

use App\Entity\Logs;
use Doctrine\ORM\EntityManagerInterface;
use Monolog\Handler\AbstractProcessingHandler;

class DoctrineHandler extends AbstractProcessingHandler
{
    private $initialized;
    private $entityManager;
    private $channel = 'doctrine_channel';

    public function __construct(EntityManagerInterface $entityManager)
    {
        parent::__construct();

        $this->entityManager = $entityManager;
    }

    protected function write(array $record): void
    {
        if (!$this->initialized) {
            $this->initialize();
        }

        if ($this->channel != $record['channel']) {
            return;
        }

        $log = new Logs();
        //$log->setMessage($record['message']);
        //$log->setLevel($record['level_name']);
        $log->setMessage($record['message']);
        $log->setLevel($record['level']);
        $log->setLevelName($record['level_name']);
        $log->setExtra($record['extra']);
        $log->setContext($record['context']);

        $this->entityManager->persist($log);
        $this->entityManager->flush();
    }

    private function initialize()
    {
        $this->initialized = true;
    }
}

Now in the sample controller file: in TestController.php

// in use inject LoggerInterface $logger
        $this->logger = $logger;
        $this->logger->info('test');

This is not logging to mysql database what is problem ? Thank you in advance for all the hints...

You need to to use bindings. Try this guide https://nehalist.io/logging-events-to-database-in-symfony/ And this https://symfony.com/blog/new-in-symfony-4-2-autowiring-by-type-and-name
