I'm new to MERN development. I'm trying to build a learning management system by following an old tutorial. But I ended up getting this error:
C:\Users\MRPla\Downloads\CourseGuccho\edemy\server\controllers\instructor.js:1
Error [ERR_REQUIRE_ESM]: require() of ES Module C:\Users\MRPla\Downloads\CourseGuccho\edemy\server\node_modules\query-string\index.js not supported.
Instead change the require of index.js in null to a dynamic import() which is available in all CommonJS modules.

The relevant code is as follows:
server>controllers>instructor.js
import User from "../models/user";
import stripe from "stripe";
import queryString from "query-string";
export const makeInstructor = async (req, res) => {
try {
// 1. find user from db
const user = await User.findById(req.user._id).exec();
// 2. if user dont have stripe_account_id yet, then create new
if (!user.stripe_account_id) {
const account = await stripe.accounts.create({ type: "express" });
// console.log('ACCOUNT => ', account.id)
user.stripe_account_id = account.id;
user.save();
}
// 3. create account link based on account id (for frontend to complete onboarding)
const accountLink = await stripe.accountLinks.create({
account: user.stripe_account_id,
refresh_url: process.env.STRIPE_REDIRECT_URL,
return_url: process.env.STRIPE_REDIRECT_URL,
type: "account_onboarding",
});
// console.log(accountLink)
// 4. pre-fill any info such as email (optional), then send url resposne to frontend
accountLink = Object.assign(accountLink, {
"stripe_user[email]": user.email,
});
// 5. then send the account link as response to fronend
res.send(`${accountLink.url}?${queryString.stringify(accountLink)}`);
} catch (err) {

if i need to change the require of index.js in null to a dynamic import() which is available in all CommonJS modules then how i will make that work?
