Entrypoint undefined = extract-text-webpack-plugin-output-filename in webpack 4

I'm using your Webpack Config file but the app.css file is not compiling in my project. I've searched and I found that Webpack no longer supports ETWP. It now supports mini-extract-text-plugin.

Kindly update your webpack.config.js file as I tried but it didn't work.
