Error [ERR_REQUIRE_ESM]: require() of ES Module not supported

Question

I'm trying to make a Discord bot that just says if someone is online on the game.

However I keep getting this message:

[ERR_REQUIRE_ESM]: require() of ES Module from not supported. Instead change the require of index.js in... to a dynamic import() which is available in all CommonJS modules.

This is my code:

    module.exports = {
        name: 'username',
        description: "this is the username command",
        async execute(message, args) {

            const fetch = require('node-fetch');

            if (args.length !== 1) {
                return message.channel.send("invalid username wtf")
            }

            const ign = args[0]

            if (ign.length > 16 || ign.length < 3) {
                return message.channel.send("invalid username wtf")
            }

            const uuid = await fetch(`https://api.mojang.com/users/profiles/minecraft/${ign}`).then(data => data.json()).then(data => data.id).catch(err => message.channel.send("error wtf"));
            const onlineInfo = await fetch(`https://api.hypixel.net/status?key=${john}&uuid=${uuid}`).then(data => data.json());

            if (uuid.length !== 32) {
                return;
            }

            if (onlineinfo.success) {
                if (onlineinfo.session.online) {
                    message.channel.send("they are online")
                }
                else {
                    message.channel.send("they are offline")
                }
            }
            else {
                message.channel.send("hypixel api bad wtf")
            }
        }
    }

This is my package.json file:

{
    "name": "discordbot",
    "version": "1.0.0",
    "main": "main.js",
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1",
        "start": "node main.js"
    },
    "author": "",
    "license": "ISC",
    "description": "",
    "dependencies": {
        "discord.js": "^13.0.1",
        "node-fetch": "^3.0.0"
    }
}

node-fetch v3 recently stopped support for the require way of importing it in favor of ES Modules. You'll need to use ESM imports now, like:

import fetch from "node-fetch";

at the top of your file.
