Wrong type for field 'callback_duration' in class 'Operation'

[immeo-rru]

Problem: the data returned from Quickpay containing data from aquirer cannot always be serialized. This results in an error that cannot be handled in my own code.

Solution: change type for field callback_duration from "string" to "int?".

Details:
Looking at the part of the JSON returned for an operaion looks like this:

{
            "id": 2,
            "type": "authorize",
            "amount": 148,
            "pending": false,
            "qp_status_code": "20000",
            "qp_status_msg": "Approved",
            "aq_status_code": "0",
            "aq_status_msg": "Accepted, The agreement has been accepted.",
            "data": {},
            "callback_url": "https://13f5-147-78-28-145.ngrok-free.app/subscriptions/callback",
            "callback_success": false,
            "callback_response_code": null,
            "callback_duration": 30002,
            "acquirer": "mobilepaysubscriptions",
            "3d_secure_status": null,
            "callback_at": "2023-09-06T11:54:00Z",
            "created_at": "2023-09-06T11:50:58Z"
 }

Test:

private string JsonOperation = @"{
		""id"": 2,
		""type"": ""authorize"",
		""amount"": 148,
		""pending"": false,
		""qp_status_code"": ""20000"",
		""qp_status_msg"": ""Approved"",
		""aq_status_code"": ""0"",
		""aq_status_msg"": ""Accepted, The agreement has been accepted."",
		""data"": { },
		""callback_url"": ""https://13f5-147-78-28-145.ngrok-free.app/subscriptions/callback"",
		""callback_success"": false,
		""callback_response_code"": null,
		""callback_duration"": 30002,
		""acquirer"": ""mobilepaysubscriptions"",
		""3d_secure_status"": null,
		""callback_at"": ""2023-09-06T11:54:00Z"",
		""created_at"": ""2023-09-06T11:50:58Z""
	}";

We are having the same issue. When retrieving data using GetAllPayments, most of the records cannot be retrieved.
