Changes Made:
Explanation:
The current bug is caused by webpack trying to retrieve hot-update.json data from localhost:5000/hot-update.json instead of localhost:5001/hot-update.json. This is fixed by updating the webpack configuration with a output.publicPath variable with the correct port number, retrieved using dotenv. Additionally, module.hot.accept and a renderApp function are added to index.js to re-render the app when changes are detected.
