Preserve object type in celery send task kwargs

Question

In the celery send task function can we preserve the type of objects passed to kwargs dictionary. The date-time values passed in the dictionary get converted to strings.

  celery_app.send_task(
    "NOTIFICATION",
    kwargs={
      "id": Id,
      "notification_endpoint": config.get("notificationEndpoint"),
      "detail": detail.to_mongo().to_dict()
    }, serializer="json")

The detail object is a nested dict with some values which are DateTime. In the NOTIFICATION task those values get converted to string.
