Cannot find module 'is-plain-object' Error when using puppeteer-extra-plugin-stealth with electron-forge with webpack template

Question

When using puppeteer-extra-plugin-stealth with electron-forge with a webpack template, when you run npm start you will get the error.

App threw an error during load
Error: Cannot find module 'is-plain-object'

I have just booted up a very basic electron-forge app based on quick start guide on their site.

Started the app and its working good. Installed the following.

• playwright
• playwright-extra
• puppeteer-extra-plugin-stealth

and just by importing puppeteer-extra-plugin-stealth is enough to trigger the error on npm start.

const { chromium } = require("playwright-extra");
const stealth = require("puppeteer-extra-plugin-stealth")();

... additional codes below ...

I tried various remedies on the internet

• added externals to webpack.main.config.js only, webpack.renderer.config.js only and both webpack.main.config.js and webpack.renderer.config.js and it doesn't work.

  externals: {
    playwright: "require('playwright')",
    "playwright-extra": "require('playwright-extra')",
    "puppeteer-extra-plugin-stealth":
      "require('puppeteer-extra-plugin-stealth')",
  },

Adding this yield another different error saying

Error: Cannot find module 'require('playwright-extra')'

• Added externals config on forge.config.js

  configureWebpack: {
    externals: {
      playwright: "require('playwright')",
      "playwright-extra": "require('playwright-extra')",
      "puppeteer-extra-plugin-stealth":
        "require('puppeteer-extra-plugin-stealth')",
    },
  },

Throws the original error

App threw an error during load
Error: Cannot find module 'is-plain-object'

Hope anyone can help me with this.

Note: I have tested using raw electron app (without electron-forge) and electron-forge without webpack template and its working good on those instances.

This is only exclusive to when using webpack as template for electron forge.
