MongoDB and Mongoose - Create and Save a Record of a Model ERROR

Hi guys
Today I am stucked at this challange. I can’t figure out what I did wrong. I just followed what the hints say.
Here is the code:

const mongoose = require("mongoose");
mongoose.connect("mongodb+srv://", { useNewUrlParser: true, useUnifiedTopology: true });

// here I create the Schema
const Schema = mongoose.Schema;
const personSchema = new Schema({
  name: { type: String, required: true },
  age: Number,
  favoriteFoods: [String]
//create the model
var Person = mongoose.model("Person", personSchema);

//create and save a record
var createAndSavePerson = function(done) {
  var roughDoor = new Person({
    name: "Rough Door",
    age: 2,
    favoriteFoods: ["meat", "meat again"]
  });, data) {
    if (err) return done.error(err);
    done(null, data);

FCC output:

// running tests
Creating and saving a db item should succeed
// tests completed

glitch project here:

What do you think I did wrong?
after I hit the button "Complete this challange " on Glitch console it says Missing done() argument. I tried to call the function createAndSavePerson and the Glitch console says “error not Handled”. I tried a Try-catch but it does the same. I looked up in internet but I found nothing.

problem solved! There was an empty function createAndSavePerson forward that was overriding the one I did before it. You just have to delete it. Then i did this:

const createAndSavePerson = function(done) {
  let roughdoor = new Person({name: 'roughdoor', age: 2, favoriteFoods: ['meat', 'meat again']});, data) => {
    if (err) return done(err);
    return done(null,data);

and it works!
