    $optionsTransfer->setType(RabbitMqConfig::EXCHANGE_DIRECT);

    $this->producerPlugin
        ->setRoutingKey('my_routing_key')
        ->publish('Testing Message..', $optionsTransfer);

    $data = ['helloWorld' => 'Message Sent !'];

    return $this->view(
        $data,
        [],
        '@HelloWorld/views/index/index.twig'
    );
}

}

It gives me error

Where do you have the RabbitMqConfig::EXCHANGE_DIRECT from? Was it somewhere documented to use it like that? because i can not find that constant in Spryker.
