script/build fails with file not found

[david-pfx]

The error is
Module not found: Error: Can't resolve 'widgets/PageNotFound.js' in ...

I think the alias in config\webpack.config.dev.js is missing from config\webpack.config.prod.js. I tried fixing that, but then there are more.

Added these two aliases:

      widgets: path.resolve(__dirname, '../src/components/widgets/'),
      utils: path.resolve(__dirname, '../src/utils/'),

Now the error is 'failed to minify'.

Failed to minify the code from this file:
        ./node_modules/query-string/index.js:8

I upgraded react-scripts, but it didn't fix the problem. Over to you.

I went back to using react-scripts and stopped using webpack aliases. It fixed the issue.
