It gives the benifit to add translations to your message, make use of error codes, set error types, set exception identifiers to track in your logging, and more ...

    "message": "A generic or custom message",
    "type": "exception types (application exception, validation exception, ... whatever you can make up)",
    "code": "an exception code that can be used on the client to set/translate exception messages client side",
    "info": object (optional object to add custom data to your client),
  },
  "status": "string",
  "statusCode": 100 // HttpStatusCode
}
