云数据库查询 and不起作用 - WXOPEN Club

云数据库and查询不管用，如下：

....

condition.a = _.gt(range[0]).and(_.lt(range[1]))

condition.b = _.gt(range[2]).and(_.lt(range[3]))

}

goodsCol.where(condition)

.limit(count).get()

.then(res =>{

....

会报错：

Uncaught (in promise) Error: errCode: -502001 database request fail | errMsg: Get Data Count Fail:(BadValue) failed on: cmgo-cn5bknzd_0 :: caused by :: $or/$and/$nor entries need to be full objects

求助！
