whereEqualTo(“type”, 1)查询不到数据

type是NUMBER类型，表里明明有数据，为什么查询到数据行数为0，注释掉这行代码就可以查了？

AVQuery<Image> query = AVQuery.getQuery("Image");
//query.whereEqualTo(Image.TYPE, 1);
query.skip(skip);
query.limit(limit);
query.include(Image.AUTHOR);
query.orderByDescending("createdAt");
images = query.find();
Log.d(TAG, "getImageByPage debug, Successful, Count = " + images.size());
