Webpack issue

[primedev22]

I've built a simple react web app with this starter-kit. The prototype is completed and now I am going to deploy it to AWS and tried to build this project and now I have unexpected error while building.

My package.json file

I have fixed this issue after upgrading webpack to version 4
