多边形内的Mongoose Geo-Query

不知怎的，我疯了，但让我解释一下 . 我有一个文档集合，其中每个文档在“loc”字段中具有GPS坐标（下面的示例） . 现在我想查询特定区域中的所有文档 . 当我使用MongoShell进行查询时，我得到了正确的结果，但是当我使用Mongoose尝试它时，每次尝试都会失败 .

正如您在下面看到的，我尝试了在Polygon坐标周围使用2和3 []的不同尝试 .

MongoDB版本：2.6.3 Mongoose版本：3.8.13

也许有人可以帮我找到类型或其他一些我看不到的愚蠢错误;-（可悲的是，错误信息“未定义不是一个功能”并没有多大帮助 .

谢谢！

Mongoose-Schema

(function () {
    module.exports = function (mongoose, Schema) {

        var PointSchema = new Schema({
            _id: Schema.ObjectId,
            loc: {
                type: { type: String },
                coordinates: { type: [Number]}
            }           
        }, { collection: "points" });
        PointSchema.index({ loc: "2dsphere" });

        mongoose.model("Point", PointSchema);
    };
})();

Sample document from the collection

{
   "_id": ObjectId("53d0d30c92a82799d8ed31d2"),
   "loc": {
     "type": "Point",
     "coordinates": {
       "0": 8.5652166666667,
       "1": 49.3288
    }
  }
}

Mongo-Shell script which works 基于：http://docs.mongodb.org/manual/reference/operator/query/geoWithin/#op._S_geoWithin

db.points.find( { loc :
                         { $geoWithin :
                            { $geometry :
                               { type : "Polygon" ,
                                 coordinates :  [[[8.594874265234353, 49.33654935186479],
