Why Upon failure SQS does not place the failed message upon DLQ?

I am running this worker:

php -d memory_limit=-1 bin/console messenger:consume sqs_channel_manager -vv

And worker fails:

14:29:32 INFO      [messenger] Received message App\Domain\Event\ChannelManager\ChannelManagerEventHasReceived ["class" => "App\Domain\Event\ChannelManager\ChannelManagerEventHasReceived"]

The transports sqs_channel_manager is configured like this:

framework:
    messenger:
        failure_transport: failed
        transports:
            failed: 'doctrine://default?table_name=failed_messages'
            sqs_channel_manager:
              dsn: 'https://sqs.eu-north-1.amazonaws.com/XXXXXX/sqs_channel_manager_test'
              serializer: App\Infrastructure\Messenger\ChannelManagerSerializer
              options:
                  access_key: '%env(AWS_ACCESS_KEY_ID)%'
                  secret_key: '%env(AWS_SECRET_ACCESS_KEY)%'
                  region: '%env(AWS_REGION)%'
                  queue_name: '%env(CHANNEL_MANAGER_QUEUE_NAME)%'

And is an SQS queue The queue has a redrive policy:

aws sqs get-queue-attributes --queue-url https://sqs.eu-north-1.amazonaws.com/XXXXXX/sqs_channel_manager_test --attribute-names RedrivePolicy
{
    "Attributes": {
        "RedrivePolicy": "{\"deadLetterTargetArn\":\"arn:aws:sqs:eu-north-1:XXXXX:sqs_channel_manager_test_dlq\",\"maxReceiveCount\":1}"
    }
}

But upon failure message is not placed upon Deal letter queue:

aws sqs get-queue-attributes --queue-url https://sqs.eu-north-1.amazonaws.com/XXXXXXXX/sqs_channel_manager_test_dlq  --attribute-names ApproximateNumberOfMessages
{
    "Attributes": {
        "ApproximateNumberOfMessages": "0"
    }
}

Does failure_transport prevents the message to be placed upon DLQ? Setting failure_transport has no effect:

            sqs_channel_manager:
              failure_transport: null
              dsn: '%env(SQS_CHANNEL_MANAGER_TRANSPORT_DSN)%'
              serializer: App\Infrastructure\Messenger\ChannelManagerSerializer
              options:
                  access_key: '%env(AWS_ACCESS_KEY_ID)%'
                  secret_key: '%env(AWS_SECRET_ACCESS_KEY)%'
                  region: '%env(AWS_REGION)%'
                  queue_name: '%env(CHANNEL_MANAGER_QUEUE_NAME)%'

Also I am using custom serializer:

<?php
declare(strict_types=1);

namespace App\Infrastructure\Messenger;

use App\Domain\Event\ChannelManager\ChannelManagerEventHasReceived;
use Symfony\Component\Messenger\Envelope;
use Symfony\Component\Messenger\Stamp\RedeliveryStamp;
use Symfony\Component\Messenger\Stamp\TransportMessageIdStamp;
use Symfony\Component\Messenger\Transport\Serialization\SerializerInterface;

class ChannelManagerSerializer implements SerializerInterface
{
    public function decode(array $encodedEnvelope): Envelope
    {
        $data = json_decode($encodedEnvelope['body'], true);

        if (json_last_error() !== JSON_ERROR_NONE) {
            throw new \InvalidArgumentException(
                'Invalid JSON received from SQS: ' . json_last_error_msg()
            );
        }

        $envelope = new Envelope(new ChannelManagerEventHasReceived($data));

        if (isset($encodedEnvelope['headers']['stamps'])) {
            $stamps = unserialize(base64_decode($encodedEnvelope['headers']['stamps']));
            foreach ($stamps as $stamp) {
                $envelope = $envelope->with($stamp);
            }
        }

        return $envelope;
    }

    public function encode(Envelope $envelope): array
    {
        $event = $envelope->getMessage();

        $stampsToSerialize = [];

        foreach ($envelope->all() as $stampArray) {
            foreach ($stampArray as $stamp) {
                if ($stamp instanceof RedeliveryStamp || $stamp instanceof TransportMessageIdStamp) {
                    $stampsToSerialize[] = $stamp;
                }
            }
        }

        return [
            'body' => json_encode($event->channelManagerData, JSON_THROW_ON_ERROR),
            'headers' => [
                'stamps' => base64_encode(serialize($stampsToSerialize)),
            ],
        ];
    }
}

Does it affect a message entering DLQ? I am using Symfony 7.2, it this a known issue?
