bug: 400 error when receiving forwarding SMS message

[oneoyz]

I have implemented the webhook API according to the example for receiving incoming message:

    [HttpPost("api/sms/incoming-sms")]
    public IActionResult ReceiveSms([FromBody] SmsInboundMessageResult smsInboundMessageResult)
    {
        foreach (var result in smsInboundMessageResult.Results)
        {
            System.Diagnostics.Debug.WriteLine($"{result.From} - {result.CleanText}");
        }
        return Ok();
    }

and have configured the HTTP forwarding in the inbound configuration correctly. However, I failed to forward my message and the infobip support provided me the logs showing it encountered bad request error.

400 Bad Request

Content-Type: application/problem+json; charset=utf-8

{"type":"https://tools.ietf.org/html/rfc9110#section-15.5.1","title":"One or more validation errors occurred.","status":400,"errors":{"incomingMessage":["The incomingMessage field is required."],"$.results[0].receivedAt":["The JSON value could not be converted to Infobip.Api.Client.Model.SmsInboundMessage. Path: $.results[0].receivedAt | LineNumber: 0 | BytePositionInLine: 169."]},"traceId":"xxxxxxxxxxxxx"}

I tested locally and found it will throw error if the receiveAt field is in 2024-12-10T15:12:28.074+0000 format instead of 2024-12-10T15:12:28.074Z, the former is the format that platform uses in forwarding message, and need to handle this situation in SmsInboundMessage
