can't fetch some field's value from rest api

I have no problem fetching id of the new case just inserted.
I would like to get description value of that case with the following code, but I failed and received an exception.
  
//Make the request
      HttpResponse response = httpClient.execute(httpPost);

      //Process the results
      int statusCode = response.getStatusLine().getStatusCode();
      if (statusCode == 201) {
        String response_string = EntityUtils.toString(response.getEntity());
        JSONObject json = new JSONObject(response_string);
        // Store the retrieved lead id to use when we update the lead.
        caseId = json.getString("id");
        System.out.println("New case id from response: " + caseId);
        Description = json.getString("Description");
        System.out.println("New case description from response: " + Description);
      } else {
        System.out.println("Insertion unsuccessful. Status code returned is " + statusCode);
      }
