Reproduction

Describe the bug

I am hosting my Nuxt project on Google Firebase.

Since upgrading to v3.0.0-rc.12, npx nuxi build no longer generates functions properly in .output\server, despite setting the preset to Firebase with the following:

export default defineNuxtConfig({
  nitro: {
    preset: 'firebase'
  }
})

The issue also occurs if using NITRO_PRESET=firebase npm run build.

When attempting preview the project locally with firebase emulators:start, the following error occurs:

i  functions: Watching "C:\Users\<...>\<repo-name>\.output\server" for Cloud Functions...
The system cannot find the path specified.

Error: An unexpected error has occurred.

Hence, the project cannot be previewed locally or deployed.

Additional context

No response
