electron and playwright scraper - cjs/loader Uncaught Error: Cannot find module 'ws'

I am trying to build an electron app with a playwright tester/scraper. If i am building in dev mode everything works. But with the electron builder packaged app i get the error at runtime:

    node:internal/modules/cjs/loader:940 Uncaught Error: Cannot find module 'ws'
Require stack:
- example.app/Contents/Resources/app.asar/dist/renderer/index.html
    at Module._resolveFilename (node:internal/modules/cjs/loader:940:15)

    at Function.resolve (node:internal/modules/cjs/helpers:108:19)
    at stackTrace.js:59:92

I am not sure if it has something to do with this issue? https://github.com/microsoft/playwright/issues/7121

My starting boilerplate was https://github.com/electron-vite/electron-vite-vue

My package.json looks like:

{
  "name": "testTool",
  "version": "1.0.0",
  "main": "dist/main/index.cjs",
  "scripts": {
    "dev": "node scripts/watch.mjs",

    ],

  }
}

In my vite.config.ts there are this:

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import resolve from 'vite-plugin-resolve'
import electron from 'vite-plugin-electron/renderer'
import pkg from '../../package.json'

// https://vitejs.dev/config/
export default defineConfig({
  mode: process.env.NODE_ENV,
  root: __dirname,
  plugins: [
    vue(),
    electron(),
    resolve(
      {
        'electron-store': 'const Store = require("electron-store"); export default Store;',
      }
    ),
  ],
  base: './',
  build: {
    outDir: '../../dist/renderer',
    emptyOutDir: true,
    sourcemap: true,
  },
  server: {
    host: pkg.env.VITE_DEV_SERVER_HOST,
    port: pkg.env.VITE_DEV_SERVER_PORT,
  },
})
