统计定点范围内的对象数量报错

db.collection('house').where({   location: _.geoNear({   geometry: db.Geo.Point(event.location.longitude, event.location.latitude),   minDistance: event.minDis,   maxDistance: event.maxDis   })   }).count()

返回

Error: errCode: -502001 database request fail | errMsg: [FailedOperation.Query] (BadValue) $geoNear, $near, and $nearSphere are not allowed in this context; 

现象和这个问题一样
