The location object is expected, the array of locations is not in the correct format

Question

I spent such a direct affair. I just want to do a CRUD operation in a user model using nodejs, mongoose, restify stack. My copy of mongo is on a mongolaba. The user must contain the "loc" field. The user schema is as follows:

var mongoose = require('mongoose')
var Schema = mongoose.Schema;
var userSchema = new Schema( {
email_id : { type: String,  unique: true },
password: { type: String},
first_name: String,
last_name: String,
age: String,
phone_number: String,
profile_picture: String,
loc: {
     type: {},
    coordinates: [Number]
}  
});
userSchema.index({loc:'2d'});
var User = mongoose.model('user', userSchema);
module.exports = User;

the rest of the api used for publishing is as follows:

create_user : function (req, res, next) {
var coords = [];
coords[0] = req.query.longitude;
coords[1] = req.query.latitude;

var user = new User(
    {
        email_id : req.params.email_id,
        password: req.params.password,
        first_name: req.params.first_name,
        last_name: req.params.last_name,
        age: req.params.age,
        phone_number: req.params.phone_number,
        profile_picture: req.params.profile_picture,
        loc: {
                type:"Point",
                coordinates: [1.0,2.0] // hardcoded just for demo
            }
    }
    ); 
user.save(function(err){ 
    if (err) { 
        res.send({'error' : err}); 
    }
        res.send(user);
    });  
return next();
},

Now when I make a POST call on curl -X POST http://localhost:3000/user --data "email_id=sdass@dfAadsfds&last_name=dass&age=28&phone_number=123456789&profile_picture=www.jakljf.com&longitude=1.0&latitude=2.0" I get the following error:

{
error: {
code: 16804
index: 0
errmsg: "insertDocument :: caused by :: 16804 location object expected,           location array not in correct format"
op: {
email_id: "[e-mail]"
password: "sdass123DadakjhdfsfadfSF45"
first_name: "shaun"
last_name: "dass"
age: "28"
phone_number: "123456789"
profile_picture: "www.jakljf.com"
loc: {
coordinates: [2]
0:  1
1:  2
-
type: "Point"
}-
_id: "55efc95e0e4556191cd36e5e"
__v: 0
}-
}-    
}

The location field gives problems because the POST call works just fine if I remove the loc field from the model

/, : 1) userSchema.index({loc:'2d'}); userSchema.index({loc:'2dsphere'}); 2) loc , Stackoverflow. , . 3) hardcode 2d, Location object expected, location array not in correct format", ?
