Getting throw error from running pug I have been trying to figure this out for a while and I have even reset the course still don't understand.

app.js:

const express = require('express');

const app = express();

app.set('view engine', 'pug');

app.get('/', (req, res) => { res.render('index'); });

app.get('/morememe', (req, res) => { res.send("<h1>Hehe boi</h1>") }) app.listen(3000, () => { console.log('The application is running on localhost:3000') }); index.pug:
