getting "MongoError: n/a" error when trying to find() with $near query

[John Lim]

i'm trying to get result near to a certain coordinate. however i'm not able to get this done, what i get is empty array although the query is execute successfully. here's my code 

var userSchema = new db.Schema({

  email: { type: String, unique: true, lowercase: true },

  password: { type: String, select: false },

  company_name: String,

  location_verified: { type:Boolean, default:false},

  account_verified: { type:Boolean, default:false},

  date_joined: {type:Date, default:Date.now},

  business_details: {

    business_phone: String,

    business_email: String,

    business_location:[]

  }

})

userSchema.index({ 'business_detail.business_location': '2d' });

var User = db.model('User', userSchema);

above is my userSchema, and below is the query i'm trying to perform. 

 var limit = req.query.limit || 10;

    // get the max distance or set it to 8 kilometers

    var maxDistance = req.query.distance || 8;

    // we need to convert the distance to radians

    // the raduis of Earth is approximately 6371 kilometers

    maxDistance /= 6371;

    // get coordinates [ <longitude> , <latitude> ]

    var coords = [];

    coords[0] = 101.6833;

    coords[1] = 3.1333;

    // find a location

    User.find({

      'business_details.business_location': {

        $near: coords,

        $maxDistance: maxDistance

      }

    }).limit(limit).exec(function(err, locations) {

      if (err) {

        console.log("The ERROR:"+err);

        //return res.json(500, err);

      }

      console.log("The RESULT:"+locations);

      //res.json(200, locations);

    });

and i'm getting this 

may i know why ? your help is appreciated. thanks

I see someone on SO spotted that your index was on the field "business_detail" but query was on "business_details".

I'm sure I've wasted hours myself looking for something that had to be obvious but not being able to see it.  :)
