Hi 👋
We have an api that can return

{
  "number": 100
}

or

{
  "number": "none"
}

depending on some conditions, how can I parse this kind of json if I want to have number: Int? as a result? If the json responds a String I wan’t the number to be null

Create a JsonTransformingSerializer that replaces "none" with null and delegate to a standard serializer afterwards 🙂
