So I pretty much keep getting a nodemon error and Im not sure as to why it keeps saying my useAndModify is an invalid option and I'm not sure as to why as this is the right way to do this code I've recheked many times and still cant find a reason as I keep getting this error Ill post the error down below

What I have tried:

<pre>import express from 'express';
import bodyParser from 'body-parser';
import mongoose from 'mongoose';
import cors from 'cors';


const app = express();

app.use(bodyParser.json({ limit: '30mb', extended: true }))
app.use(bodyParser.urlencoded({ limit: '30mb', extended: true }))
app.use(cors());


const CONNECTION_URL = 'mongodb+srv://Miles:Morales@cluster0.lic6t.mongodb.net/myFirstDatabase?retryWrites=true&w=majority';
const PORT = process.env.PORT || 5000;

mongoose.connect(CONNECTION_URL, { useNewUrlParser: true, useUnifiedTopology: true })
    .then(() => app.listen(PORT, () => console.log(`Server Running on Port: ${PORT}`)))
    .catch((error) => console.log(`${error} did not connect`));

mongoose.set('useFindAndModify', false);
