Building multiple entry points fails most of the time

[LokiMidgard]

I try to build (npm run build) multiple entry points for my app. This fails most of the time. Building 6 times only works once (not statistically correct).

I don't change anything between builds, just execute npm run build until it works. Executing it again after a success has a high probability of failure.

I have a test project to demonstrate this.

The webpack.config.js I try to build:

const path = require('path');

function makeWebpack(inputPath) {
  if (inputPath.length > 0 && !inputPath.startsWith('/')) {
    inputPath = '/' + inputPath;
  }
  return webpackMerge(
    webpackConfig,
    htmlOverlay({
      template: 'public/index.html'
    }),
    {
      entry: './src' + inputPath + '/index',
      output: {
        path: path.join(process.cwd(), 'dist/', inputPath),
      }
    }
  );
};

const { webpackMerge, htmlOverlay, webpackConfig } = require('just-scripts');
module.exports = [
  makeWebpack(''),
  makeWebpack('S1'),
];

The error I get when it is not working:
