How to add GeoJson data with mongoose?

I am sending the object to create a user model.

"{ 
type: 'Point', 
coordinates: [ 25.2239771, 51.4993224 ] 
}"

And, here is the Mongoose Schema that I created.

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const UserProfileSchema = new Schema(
  {
 
    userId: {
      type: String,
      // required: true,
      unique: true,
    },
    userFirstName: {
      type: String,
      // required: true,
    },
    userLastName: {
      type: String,
      // required: true,
    },
    userGender: {
      type: String,
      // required: true,
    },
    
    userCoordinates: {
      type: {
        type: String,
        default: 'Point',
      },
      coordinates: {
        type: [Number],
        index: '2dsphere',
      },       
    },
  },
  { collection: 'userprofilemodels' }
);

module.exports = UserProfile = mongoose.model(
  'userprofilemodels',
  UserProfileSchema
);

This is the code that I am using to add geoJson type file. However, I am getting an error. I also tried to add index after the Schema has been defined

await new userProfileModel({
        userId,
        userFirstName,
        userLastName,
        userCoordinates,

      })
        .save()
        .then(() => {
          console.log('it worked!');
          res.send('worked!');
        })
        .catch((error) => {
          console.log('did not worl')
          // console.log(error);
        });

If I exclude userCoordinates, then it works. So, def my geoJson object is wrong. However, I have no clue where I have made mistakes.

Mongoose supports GeoJSON objects indexing so first add the "2dsphere" index to the userCoordintes rather than to the coordinates within the object in order to make it work.

userCoordinates: {
      type: {
        type: String,
        default: 'Point',
      },
      coordinates: {
        type: [Number],
        default: undefined,
        required: true
      },
      index: '2dsphere'       
},

Make sure your userCoordinates looks something like this:

const userCoordinates = {
        type: "Point",
        coordinates: [coordinatesA, coordinatesB],
};

Taken from the mongoose documentation it seems the GeoJSON Type mustn't be only a String.

here is the example with location as a GeoJSON type:

const citySchema = new mongoose.Schema({
  name: String,
  location: {
    type: {
      type: String, // Don't do `{ location: { type: String } }`
      enum: ['Point'], // 'location.type' must be 'Point'
      required: true
    },
    coordinates: {
      type: [Number],
      required: true
    }
  }
});
