Error deserializing the object DateTime content in Azure Function

Question

Hi Team,

I have been working on Azure function , where i have been reading Json Data(Dynamics CRM Json Data) in ServiceBusTrigger .

I am reading Json Data using Remote Execution Context property however i am getting error while desterilizing content (Error - There was an error deserializing the object of type Microsoft.Xrm.Sdk.RemoteExecutionContext. DateTime content '2025-06-02T05:57:00.679Z' does not start with '/Date(' and end with ')/' as required for JSON).

Can you pls assist me how to read Input Parameter Collection attributes data in Azure ?

Following JSON data i am passing to above Service Bus Trigger

Hi @Prashant S Miraje,

Initially after using the code provided, I have also got similar error:

Json Used:

{
  "BusinessUnitId": "b1280Rithwik819e439",
  "CorrelationId": "65e4588Chotub4fb",
  "Depth": 1,
  "InitiatingUserId": "b12f046Bojjae439",
  "MessageName": "Update",
  "Mode": 0,
  "OperationCreatedOn": "2025-06-02T05:57:00.679Z",
  "OrganizationId": "3dba6bbValueed6f8d",
  "PrimaryEntityId": "a127b3f4Emod599559",
  "InputParameters": [
    {
      "key": "Target",
      "value": {
        "__type": "Entity:http://schemas.microsoft.com/xrm/2011/Contracts",
        "Attributes": [
          {
            "key": "name",
            "value": "Contoso Inc."
          },
          {
            "key": "modifiedon",
            "value": "2025-06-02T05:56:59Z"
          }
        ],
        "Id": "a127basala99559",
        "LogicalName": "account"
      }
    }
  ]
}

Error:

The Newtonsoft.Json serializer correctly handles standard ISO 8601 date formats (like "2025-06-02T05:57:00.679Z"), whereas the older WCF-style serializer is much stricter — it only accepts dates in the legacy \/Date(milliseconds)\/ format (e.g., "\/Date(1717307820679)\/"), and cannot parse ISO 8601 strings.

Then tried to change to below code which works:

function.cs:

using Newtonsoft.Json;
using Microsoft.Azure.Functions.Worker;
using Azure.Messaging.ServiceBus;
using Microsoft.Extensions.Logging;
using System.Threading.Tasks;
using Microsoft.Xrm.Sdk;

public class Function1
{
    private readonly ILogger chlg;

    public Function1(ILogger<Function1> lg)
    {
        chlg = lg;
    }

    [Function(nameof(Function1))]
    public async Task Run(
        [ServiceBusTrigger("myqueue", Connection = "rithcon")] ServiceBusReceivedMessage message, ServiceBusMessageActions messageActions)
    {
        var json = message.Body.ToString();
        chlg.LogInformation("Raw JSON received: {json}", json);
        var rithexecntxt = JsonConvert.DeserializeObject<RemoteExecutionContext>(json);
        chlg.LogInformation("Deserialized CorrelationId: {id}", rithexecntxt.CorrelationId);
        if (rithexecntxt.SharedVariables != null)
        {
            foreach (var kvp in rithexecntxt.SharedVariables)
            {
                if (kvp.Value is DateTime dt)
                {
                    chlg.LogInformation("SharedVariable {key} has DateTime value: {value}", kvp.Key, dt.ToString("o"));
                }
            }
        }
        if (rithexecntxt.OperationCreatedOn != DateTime.MinValue)
        {
            chlg.LogInformation("Rithwik the OperationCreatedOn is {timestamp}", rithexecntxt.OperationCreatedOn.ToString("o"));
        }
        await messageActions.CompleteMessageAsync(message);
    }
}
