Uncaught ReferenceError: amadeus is not defined at REPL16:1:39 while saving data using mongoose

Question

Encountered an error while trying to save data in mongoDB using mongoose.

index.js file -

const mongoose = require('mongoose')
mongoose.connect('mongodb://127.0.0.1:27017/myapp')
    .then(() => {
        console.log("Connection established!")
    })
    .catch((e) => {
        console.log("Error!")
        console.log(e)
    })
    
const movieSchema = new mongoose.Schema({
    title: String,
    year: Number,
    score: Number,
    rating: String
})

const Movie = mongoose.model('Movie', movieSchema)
const amadeus = new Movie({ title: 'Amadeus', year: 1984, score: 8.4, rating: 'PG'})

I loaded this file from node terminal using - .load index.js and then tried to save amadeus using - amadeus.save() but it gave this error:

Uncaught ReferenceError: amadeus is not defined at REPL16:1:39

But the 'myapp' db and 'movies' collection was created and I'm able to access it from mongo shell.

One solution to the above problem is to run the index.js file using - node -i -e "$(< index.js)" inside the system terminal and not inside the node shell. The reason of this error is maybe related to the new version of Node.js
