I am getting duplicate key error while doing the POST action. I don’t want it to be unique.

error : MongoError: E11000 duplicate key error collection:
timeformationBD.formations index: description_1 dup key: { : null }

This is my formations route:-

const express = require('express');
const router = express.Router();
const Formation = require('../models/formations');
const config = require('../config/database');

router.get('/', function(req, res) {
  Formation.getFormations(function(err, formations) {
    if (err) throw err;
    res.json(formations);
  });
});

router.post('/', function(req, res) {
  let newFormation = new Formation({    
    name: req.body.name,
    email: req.body.email,
    username: req.body.username,
    password: req.body.password
  });
  Formation.addFormation(newFormation, function(err, formation) {
    if (err) throw err;
    res.json(formation);
  });
});
    
router.put('/:_id', function(req, res) {    
  let update = new Formation({
    name: req.body.name,
    email: req.body.email,
    username: req.body.username,
    password: req.body.password
  });
  Formation.updateFormation(req.params._id, update, function(err, formation) {
    if (err) throw err;
    res.json(formation);
  });
});

router.get('/:_id', function(req, res) {
  Formation.getFormation(req.params._id, function(err, formation) {
    if (err) throw err;
    res.json(formation);
  });
});

router.delete('/:_id', function(req, res) {
  Formation.deleteFormation(req.params._id, function(err, formation) {
    if (err) throw err;
    res.json(formation);
  });
});
    
module.exports = router;

This is my formations models:-

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const config = require('../config/database');    
const FormationSchema = mongoose.Schema({
  name: {
    type: String
  },
  email: {
    type: String
  },
  username: {
    type: String
  },
  password: {
    type: String
  } 
});

const Formation = module.exports = mongoose.model('Formation', FormationSchema);    

module.exports.getFormations = function(callback) {
  Formation.find(callback);    
}

module.exports.addFormation = function(newFormation, callback) {
  Formation.create(newFormation, callback);    
}

module.exports.updateFormation = function(callback) {
  Formation.findByIdAndUpdate(id, newFormation, callback);    
}

module.exports.deleteFormation = function(callback) {
  Formation.findByIdAndRemove(id, callback);    
}

module.exports.getFormation = function(callback) {
  Formation.findById(id, callback);    
}
