代码如下：想查询num大于1的数据  return db.collection('amount').aggregate()     .group({       _id: '$openid',       num: $.sum(1)     })     .match({num:_.gt(1)})     .end()     .then((result)=>{       console.log(result)     }) 报错如下： {"errorCode":1,"errorMessage":"user code exception caught","stackTrace":"Error: collection.aggregate:fail -502001 database request fail.
