I'm unable to build my react project using npm run build as I keep getting the error message below:

Child __offline_serviceworker:
     1 asset
    Entrypoint __offline_serviceworker = __offline_serviceworker
Child html-webpack-plugin for "index.html":
     1 asset
    Entrypoint html-webpack-plugin for "index.html" = index.html

I'm fairly new to building react projects so apologies if this is an amateur question. What I've tried already:

1. I've tried changing the entry point by following this html-webpack-plugin Entrypoint undefined = index.html but it still hasn't worked.

2. I've attempted downgrading webpack to 3.07 as well but that solution didn't help either.

3. I've tried other options including npm i mishoo/UglifyJS2#harmony in terminal as pointed out here: https://github.com/webpack/webpack-pwa/issues/7 but still no luck

I currently can't think of any other solution thus I decided to post here.

My webpack is located in: internals/webpack/webpack.prod.babel

My index.html is located in the root folder

In my package.json, I have webpack as follows:

"devDependencies": {
 "html-webpack-plugin": "3.0.7",
...
}

I'd totally appreciate help to help resolve this issue. Thanks in advance everyone.
