Javascript 未成功编辑分析对象

我正在编写一个函数，用于查询与相应用户关联的matchCenterItem对象的解析，然后编辑该对象的某些属性。进行查询时，响应结果以以下形式返回：

<matchCenterItem: 0x7f84e2c1a4b0, objectId: Je1VxP7dPw, localId: (null)> {
    categoryId = 9355;
    itemCondition = Used;
    itemLocation = US;
    maxPrice = 350;
    minPrice = 250;
    parent = "<PFUser: 0x7f84e2c20c10, objectId: kfEHfG4FUD>";
    searchTerm = "iphone 5 unlocked";
}

将代码更改为此，现在可以使用：

Parse.Cloud.define("editMatchCenter", function(request, response) {

  var matchCenterItem = Parse.Object.extend("matchCenterItem");
  var query = new Parse.Query(matchCenterItem);

  query.contains('searchTerm', request.params.searchTerm);
  query.equalTo('parent', Parse.User.current())

  query.first({
    success: function(results) {

      results.set('minPrice', request.params.minPrice);
      results.set('maxPrice', request.params.maxPrice);
      results.set('itemCondition', request.params.itemCondition);
      results.set('itemLocation', request.params.itemLocation);
      results.save();

      response.success('MatchCenterItem successfully edited!');

    },
    error: function() {
      response.error('MatchCenterItem NAAAAT successfully edited!');
    }
  });

});

Parse.Cloud.define("editMatchCenter", function(request, response) {

  var matchCenterItem = Parse.Object.extend("matchCenterItem");
  var query = new Parse.Query(matchCenterItem);

  query.contains('searchTerm', request.params.searchTerm);
  query.equalTo('parent', Parse.User.current())

  query.first({
    success: function(results) {

      results.set('minPrice', request.params.minPrice);
      results.set('maxPrice', request.params.maxPrice);
      results.set('itemCondition', request.params.itemCondition);
      results.set('itemLocation', request.params.itemLocation);
      results.save();

      response.success('MatchCenterItem successfully edited!');

    },
    error: function() {
      response.error('MatchCenterItem NAAAAT successfully edited!');
    }
  });

});
