Symfony Messenger / RabbitMQ detecting requed messages - configuration

Question

If consuming message fails message is re-queued with a delay by default.
Is there a way to add a counter to a message so I could know if message is on its last attempt?
This is desired behavior:
First attempt:
App\Message\Message {
body: array:2 [
"id" => 2
"alias" => "some_alias",
"attempt" => 0,
]
}
First retry:
App\Message\Message {
body: array:2 [
"id" => 2
"alias" => "some_alias",
"attempt" => 1,
]
}
Second retry:
App\Message\Message {
body: array:2 [
"id" => 2
"alias" => "some_alias",
"attempt" => 2,
]
}
Third retry:
App\Message\Message {
body: array:2 [
"id" => 2
"alias" => "some_alias",
"attempt" => 3,
]
}

Solution
messenger.yaml:
...
buses:
messenger.bus.default:
middleware:
# service ids that implement Symfony\Component\Messenger\Middleware
- 'App\Middleware\RetryMiddleware'
...
App\Middleware\RetryMiddleware:
namespace App\MessageMiddleware;
use Symfony\Component\Messenger\Middleware\MiddlewareInterface;
use Symfony\Component\Messenger\Envelope;
use Symfony\Component\Messenger\Middleware\StackInterface;
use Psr\Log\LoggerInterface;
class RetryMiddleware implements MiddlewareInterface
{
public function handle(Envelope $envelope, StackInterface $stack): Envelope
{
try {
return $stack->next()->handle($envelope, $stack);
} catch (\Throwable $error) {
$msg = $envelope->getMessage();
$body = $msg->getBody();
$body['attempt']++;
$msg->setBody($body);
//rethrow same error
throw $error;
}
}
}
App\Message:
namespace App\Message;
class Message
{
public $body;
public function getBody()
{
return $this->body;
}
public function setBody(array $body): void
{
$this->body = $body;
}
}
