Actual Behaviour

Steps to reproduce

Provide your webpack config

Provide your Environment details

• Node version:

• Operating System:

• webpack version:

• parallel-webpack version:

With this webpack.renderer.js :

/* eslint-disable @typescript-eslint/no-var-requires */
const rules = require('./webpack.rules');
const plugins = require('./webpack.plugins');
const aliases = require('./webpack.aliases');

module.exports = {
  // https://github.com/electron/electron/issues/9920
  //target: 'electron-renderer',
  target: 'web',
  module: {
    rules,
  },
  plugins: plugins,
  resolve: {
    extensions: ['.js', '.ts', '.jsx', '.tsx', '.css'],
    alias: {
      // React Hot Loader Patch
      'react-dom': '@hot-loader/react-dom',
      // Custom Aliases
      ...aliases,
    },
  },
};

The electron app works fine:

Now, since I need multiple configurations, based on the example: https://github.com/trivago/parallel-webpack#variants-example ,
I tried to use parallel-webpack in this way:

/* eslint-disable @typescript-eslint/no-var-requires */
const rules = require('./webpack.rules');
const plugins = require('./webpack.plugins');
const aliases = require('./webpack.aliases');

// https://webpack.js.org/concepts/targets/#multiple-targets
// https://github.com/trivago/parallel-webpack#variants-example

var createVariants = require('parallel-webpack').createVariants;

var baseOptions = {
    preferredRules: rules,
    preferredPlugins: plugins,
    preferredExtensions: ['.js', '.ts', '.jsx', '.tsx', '.css'],
    preferredAliases: aliases
};

var variants = {
    target: ['electron-renderer', 'electron-main', 'web']
};

function createConfig(options) {
  return {
    target: options.target,
    module: {
      rules: preferredRules,
    },
    plugins: preferredPlugins,
    resolve: {
      extensions: preferredExtensions,
      alias: {
        // React Hot Loader Patch
        'react-dom': '@hot-loader/react-dom',
        // Custom Aliases
        ...preferredAliases,
      }
    }
  }
}

But I get this error:

devDependencies:

  "node-loader": "^1.0.1",
  "parallel-webpack": "^2.6.0",
  "electron": "^11.2.1",
  "typescript": "^4.0.2",
  "webpack": "4"

OS: Ubuntu 18.04.4 Desktop
node: v14.5.0

Here I've put the simple repo, so you can check yourself and easily spot the problem: https://github.com/raphael10-collab/OnlyLibp2p

Just git clone it ----> yarn ---> yarn start
