Cannot create Mongoose Object with location field

Question

Using Mongoose, I can't insert location data into the database :

Can't extract geo keys from object, malformed geometry?

It seems that the POST request is OK (LOG A) : It has a location ('loc') field, but the object I create from this POST request is missing the 'loc' field data :

Here is my Schema :

models/Article.js

var ArticleSchema = new mongoose.Schema({
    slug: {type: String, lowercase: true, unique: true},
    title: String,
    description: String,
    body: String,
    loc :  { type: {type:String}, coordinates: [Number]},
    favoritesCount: {type: Number, default: 0},
    comments: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Comment' }],
    tagList: [{ type: String }],
    author: { type: mongoose.Schema.Types.ObjectId, ref: 'User' }
}, {timestamps: true});

ArticleSchema.index({loc: '2dsphere'});

routes/Article.js

router.post('/', auth.required, function(req, res, next) {
  User.findById(req.payload.id).then(function(user){
      if (!user) { return res.sendStatus(401); }

      var article = new Article(req.body.article);

      // LOG A
      console.log(req.body.article);

      // LOG B
      console.log(article);

      article.author = user;

      return article.save().then(function(){
         return res.json({article: article.toJSONFor(user)});
      });
      ...

And here are the output :

LOG A : req.body.article

{ title: 'article title',
  description: 'about section',
  body: 'Article body',
  tagList: [],
  loc: '{"type":"Point","coordinates":[38.9173025,-77.220978]}' 
}

LOG B : article created with var article = new Article(req.body.article);

{ loc: { coordinates: [] },
  favoritesCount: 0,
  comments: [],
  tagList: [],
  _id: 5a384f502c9912312c6dd89d,
  body: 'Article body',
  description: 'about section',
  title: 'article title' 
}

My problem, is that the loc field began "{ coordinates: [] }" instead of {"type":"Point","coordinates":[38.9173025,-77.220978]} when creating the objet "Article".

Why is that the location data isn't in the Object ?

I've been looking a this question first : Location in mongoose, mongoDB

Can`t cast it because it is string (note the single quotes around the value for loc variable in Log A output ) whereas mongoose expects object ? — s7vr, Dec 19 '17 at 00:19

Thanks to @Veeram : The problem was my POST request : The location was sent as string instead of an object :

In my Angular front-end :

article.model.ts BEFORE

export class Article {
  ....
  loc: string
  ....
}

article.model.ts AFTER

class Location {
  constructor(
    public type: string,
    public coordinates: Array<number> = []
  ){}
}

export class Article {
  ....
  loc: Location
  ....
}
