猫鼬无法对位置数组执行$ near查询

Question

I've tried looking for solutions and I've read parts of the documentation for the $near and $geoNear queries but I have not been successful.

var userSchema = new Schema({
  zipcode : {
    formatted : {type : String, required : false, default : ""},
    geo : { type: [Number], default: [0,0]} // long, lat
  }
});
userSchema.index({"zipcode.geo" : '2d'});

ON A DIFFERENT FILE

var locationSchema = new Schema({
  formatted : {type : String, unique : false, required : true},
  geo : { type: [Number], default: [0,0]}
});

locationSchema.index({geo: '2d'});

var storeSchema = new Schema({
  locations : [locationSchema],
});

On my controller

let nearQuery = {
  $near : [ user.zipcode.geo[0], user.zipcode.geo[1]],
  spherical: true,
  $maxDistance: 7000
}
Stores.find(locations : nearQuery).exec(function(error, doc) {

});

But i end up getting the error - "Error: Can't use spherical with Array."

When I remove

spherical : true

I get the error - " planner returned error: unable to find index for $geoNear query"

I know i am doing something wrong, I just cant figure out how to fix it. How can I fix this? or What is the best way of doing this?

Thank you in advance.

Turns out I was using the wrong syntax for the query and was trying to run the query on the locations field, while I should have done it on the locations.geo field.
