Can't seem to pass MongoDB and Mongoose - Create and Save a Record of a Model

Hello guys, I can’t seem to find the solution to this test and can’t understand what is wrong with my code. I keep getting “Missing callback argument” response from the tests. Below is my code.

const mongoose = require('mongoose');

mongoose.connect(process.env.MONGO_URI, {useNewUrlParser: true});

const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error: '));
db.once('open', function(){
  console.log("We're connected!");

var Schema = mongoose.Schema;

var personSchema = new Schema({
  name: {
    type: String,
    required: true
  age: {
    type: Number,
    required: true
  favoriteFoods: {
    type: Array,
    required: true

var Person = mongoose.model('Person', personSchema);

var createAndSavePerson = function(done) {
 var person = new Person({name: "Pedro", age: 25, favoriteFoods: ["Steak", "Pizza", "Tacos"]});, data) => err ? done(err) : done(null, data));

I’m starting to think that this test is broken so I’m really eager to hear your opinion’s about this. Thanks in advance.

Your function createAndSavePerson is declared but never executed.
