附表排序不生效。是不是附表不支持排序？

const db = uniCloud.databaseForJQL()
const tong_baogao = db.collection('tong_baogao').field('uid,shikuai_type,serial_number,testing_intensity').getTemp();
const taizhang = db.collection('taizhang').field('_id,part,intensity,jiaozhu_date,lotsize').orderBy(lotsize','desc').getTemp()
console.log(tong_baogao,"台账");
await db.collection(tong_baogao, taizhang) .get()

请问好心大哥：是不是附表的orderBy(lotsize','desc')方法不能使用？
