Named export 'defu' not found

[DesertCookie]

I created a fresh Nuxt project using bun and installed PWA. When I run the application via npm run dev, I get the following error:

 ERROR  Named export 'defu' not found. The requested module 'defu' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'defu';
const { defu } = pkg;


  import { defu } from 'defu';
  ^^^^

This is my package.json:

{
  "name": "project",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "nuxt build",
    "dev": "nuxt dev --tunnel",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "dependencies": {
    "nuxt": "^3.13.0",
    "vue": "latest",
    "vue-router": "latest"
  },
  "devDependencies": {
    "@nuxtjs/pwa": "^3.3.5"
  }
}

My nuxt.config.ts:

export default defineNuxtConfig({
	devtools: {enabled: true},
	buildModules: [
		'@nuxtjs/pwa',
	],
	pwa: {
		manifest: {
			name: 'Immo-Projektmanagement',
			short_name: 'ImmoM',
			description: '',
			lang: 'de'
		},
		workbox: {},
		mobileAppIOS: true
	},
	compatibilityDate: '2024-09-09'
})

I was in the process of migrating an app to a PWA and had started a new project for that purpose to slowly transition all aspects of the app.

Running npx nuxi upgrade --foce gives me a different error now:

    throw new ERR_MODULE_NOT_FOUND(
          ^

Node.js v22.8.0

I have since upgraded my Node version which was formerly v21.x.

Edit: It's back to the Defu error.
