Share session not working

[krajcikondra]

Hi,

I am using symfony 5 with web server running by following command:
symfony server:start
and websocket server by command

php bin/console gos:websocket:server
Web server running on 127.0.0.1:8000
Websocket server running on 127.0.0.1:8888

I am using session store in database.

My configuration

gos_web_socket:
    server:
        port: 8888        # The port the socket server will listen on
        host: 127.0.0.1   # The host ip to bind to
        router:
            resources:
                - '%kernel.project_dir%/config/pubsub/routing.yaml'
    client:
        firewall: main # Can be an array of firewalls
        session_handler: 'session.handler.pdo'

services:
    app.websocket.topic.acme:
        class: App\Websocket\Topic\AcmeTopic
        tags:
            - { name: gos_web_socket.topic }

    session.handler.pdo:
        class: Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler
        arguments:
            - !service { class: PDO, factory: ['@database_connection', 'getWrappedConnection'] }
            - { lock_mode: 0 }

And when i dump sessionId in AcmeTopic::onPublish method

   public function onPublish(
        ConnectionInterface $connection,
        Topic $topic,
        WampRequest $request,
        $event,
        array $exclude,
        array $eligible
    ): void {

    	var_dump($event);
    	$this->logger->log('info', 'sessionId = ' . $connection->WAMP->sessionId);
    	var_dump('session', $connection->WAMP->sessionId);
    	...

framework.yaml

framework:
    secret: '%env(APP_SECRET)%'
    #csrf_protection: true
    #http_method_override: true

    # Enables session support. Note that the session will ONLY be started if you read or write from it.
    # Remove or comment this section to explicitly disable session support.
    session:
        handler_id: 'session.handler.pdo'
        name: 'PHPSESSID' # in php.ini is session name set to PHPSESSID too
        cookie_secure: auto
#        cookie_samesite: lax

then i get different sessionId (anonymouse) as expected.

Know somebody what I do wrong?
