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.

I have to run cd .output/server && rm -rf node_modules && npm i after each npx nuxi build, so no, this is only a workaround and it is not resolved I believe.

firebase-functions recently upgraded from v3 to v4 which included a number of breaking changes - I wonder whether this is causing any issues if Nitro is still based on v3?

A temporary solution that worked for me is to reinstall the node modules in the .output/folder directory:

cd .output/server && rm -rf node_modules && npm i
