Delivery info have no ApproximateReceiveCount

[F1ashhimself]

Versions:

• Python 3.10
• Celery 5.3.4
• Kombu 5.3.2

---

After updating celery and kombu to latest versions I have stopped receiving ApproximateReceiveCount in delivery_info properties. With celery 5.3.1 and kombu 5.3.1 all works fine and properties contains ApproximateReceiveCount field.

{
    "body_encoding": "base64",
    "correlation_id": "<correlation_id_hidden>",
    "delivery_info": {
        "exchange": "",
        "routing_key": "celery",
        "sqs_message": {
            "Attributes": {
                "ApproximateReceiveCount": "1"
            },
            "Body": "<body_hidden>"
        },
        "sqs_queue": "<sqs_hidden>"
    },
    "delivery_mode": 2,
    "delivery_tag": "<delivery_tag_hidden>",
    "priority": 0,
    "reply_to": "<reply_to_hidden>"
}

Hi @F1ashhimself, I'm not the expert on this issue, however it could be that this was introduced in kombu 5.3.2 due to a big change in SQS see #1726 and #1759. Although that code change still had some reference to ApproximateReceiveCount, your report show that it looks like it did not include the attribute.

That change was reverted in kombu 5.3.3, see #1799. So perhaps that version has the attribute again. I'm unable to verify that, perhaps you can do that.

We have to keep your report in mind in case another try is made #1726 as it looks like a change in behaviour.
