Deploying Firebase user().onCreate() Function, undefined 'user' error [duplicate]

Question

This is my index.js file:

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp();

exports.createUser = functions.auth.user().onCreate((user) => {
    console.log('user')
})

Whenever, I try to run it in a firebase emulator or deploy it, I get this error message:

TypeError: Cannot read properties of undefined (reading 'user')
    at Object.<anonymous> (C:\Users\cwrig\Desktop\gen_mc_skins\front-end-mc-skins\functions\index.js:7:37)

Furthermore, when I am trying to develop the function and i type functions. I do not see auth popup in ide to autofill.

I have been researching for a few hours, and cannot see what I am missing. I made sure I am on node version 22. I am on firebase tools version: 13.35.1

I have deleted and recreated the firebase functions directory.

I am sure it might just be something small, but nothing I do is fixing it, and documentation seems a little bit out of date to me
