DevTools Not Working in Nuxt with Storybook

Description

When using the latest versions of Nuxt and Storybook, Vue DevTools and Nuxt DevTools do not work as expected. I encounter the following errors when running npx nuxt storybook:

Errors (translated to English)

1. WebSocket Connection Error:

   Firefox cannot establish a connection to the server at ws://localhost:6006/_nuxt/. client:535:18
   

2. DOMException:

   Uncaught (in promise) DOMException: An invalid or illegal string was specified
       NuxtJS 5
           setupWebSocket
           fallback
           setupWebSocket
           setupWebSocket
           <anonymous>

Reproduction Steps

1. Initialize a new Nuxt project.
2. Add Storybook using @nuxtjs/storybook and @storybook-vue/nuxt.
3. Start Storybook using npx nuxt storybook.
4. Open the browser and check for Vue or Nuxt DevTools availability.

Expected Behavior

• Vue DevTools should load properly in the browser.
• Nuxt DevTools should be accessible via Shift + Alt + D.

What I Tried

1. Creating a Nuxt plugin to enable Vue DevTools explicitly:

   export default defineNuxtPlugin((nuxtApp) => {
     if (import.meta.env.DEV && process.client) {
       const app = nuxtApp.vueApp;
       app.config.devtools = true;
       console.log("Vue DevTools enabled");
     }
   });

   However, this did not resolve the issue.

2. Ensuring HMR configuration in nuxt.config.ts:

   export default defineNuxtConfig({
     vite: {
       server: {
         hmr: {
           protocol: 'ws',
           host: 'localhost',
           port: 24678, // Port for Nuxt DevTools
         },
       },
     },
     devtools: {
       enabled: true,
     },
   });

   This also did not work, and the WebSocket error persists.

Current Environment

Here’s my package.json:

{
  "dependencies": {
    "@radix-ui/colors": "^3.0.0",
    "@unocss/reset": "^0.64.0",
    "nuxt": "latest",
    "radix-vue": "^1.9.9",
    "vue": "latest",
    "vue-router": "latest"
  },
  "devDependencies": {
    "@chromatic-com/storybook": "^1.9.0",

  }
}

Additional Notes

• The issue seems to be a conflict between Storybook's WebSocket server and Nuxt DevTools.
• I suspect that Storybook might be overriding or interfering with Nuxt's WebSocket configurations (ws://localhost:6006/_nuxt/).

Environment Details

• Nuxt Version: Latest
• Storybook Version: 8.4.2
• Node Version: 18.17.5
• Browser: Firefox (latest)

Question

Why is Storybook or Nuxt setting Vue.config.devtools = false by default when running npx nuxt storybook? Is there a way to ensure both Nuxt DevTools and Storybook can coexist without these conflicts?

Let me know if you'd like to clarify anything else or add further details!
