I am unable to seed my mongodb with some sample data

Question

I am learning React through a tutorial made by Mosh Hamadani(CodeWithMosh). In the section where we are supposed to learn how to connect the front end with the back end I encountered an error. I made sure I did everything according to the video but I had no success to seed my database. The following code below is my sample data and the image after is the error I got when I run node seed.js just like the instructor did. Please help me.

const { Genre } = require("./models/genre");
const { Movie } = require("./models/movie");
const mongoose = require("mongoose");
const config = require("config");

const data = [
  {
    name: "Comedy",
    movies: [
      { title: "Airplane", numberInStock: 5, dailyRentalRate: 2 },
      { title: "The Hangover", numberInStock: 10, dailyRentalRate: 2 },
      { title: "Wedding Crashers", numberInStock: 15, dailyRentalRate: 2 },
    ],
  },
  {
    name: "Action",
    movies: [
      { title: "Die Hard", numberInStock: 5, dailyRentalRate: 2 },
      { title: "Terminator", numberInStock: 10, dailyRentalRate: 2 },
      { title: "The Avengers", numberInStock: 15, dailyRentalRate: 2 },
    ],
  },
  {
    name: "Romance",
    movies: [
      { title: "The Notebook", numberInStock: 5, dailyRentalRate: 2 },
      { title: "When Harry Met Sally", numberInStock: 10, dailyRentalRate: 2 },
      { title: "Pretty Woman", numberInStock: 15, dailyRentalRate: 2 },
    ],
  },
  {
    name: "Thriller",
    movies: [
      { title: "The Sixth Sense", numberInStock: 5, dailyRentalRate: 2 },
      { title: "Gone Girl", numberInStock: 10, dailyRentalRate: 2 },
      { title: "The Others", numberInStock: 15, dailyRentalRate: 2 },
    ],
  },
];

async function seed() {
  await mongoose.connect(config.get("db"));

  await Movie.deleteMany({});
  await Genre.deleteMany({});

  for (let genre of data) {
    const { _id: genreId } = await new Genre({ name: genre.name }).save();
    const movies = genre.movies.map((movie) => ({
      ...movie,
      genre: { _id: genreId, name: genre.name },
    }));
    await Movie.insertMany(movies);
  }

  mongoose.disconnect();

  console.info("Done!");
}

seed();

This is my first time using mongodb. I tried to check their website for clue on how to seed my database. I copy and pasted the code I found here. This time the error I got was check image for the error. I tried to install the 'faker module' for still nothing.
