Replace your user ID and Password there and don't add extra spaces anywhere in this file

i didn't reach that point yet, i am still at 1:04:48 in the video

the index file look like this :

import express from 'express' ;
import * as dotenv from 'dotenv';
import cors from 'cors';

dotenv.config();

const app = express();
app.use(cors());
app.use(express.json({ limit: '50mb' }));

app.get('/', async (req, res) => {
res.send('Hello from Dall-E');
});

const startServer = async () => {
app.listen(8080, () => console.log('Server has started on port http://localhost:8080'));
};
startServer();

You had run another server use the same port like 8080.

Maybe you had run node app in other shell, Please close it and run again.
