Finally, Nitro seems to detect the deployment environment (see Zero-Config Providers doc), and select the right preset (in this case cloudflare_pages I presume). In the Nitro clouldflare.ts, we can see :

...
output: {
    serverDir: '{{ rootDir }}/functions'
},
...

The server directory /functions folder is emptied before each Nitro prerender. I suppose that Nuxt 3 /server folder should be used as source of functions folder but there’s some issues.

I fixed the problem by setting the environment variable NITRO_PRESET=node-server in CF settings.

Also, it’s important that you run nuxt build rather than nuxt generate. When you choose the Nuxt preset, it chooses npm run generate as the default build command and /dist as the output directory.

Unfortunately that does not help those of us that that DO NOT want SSR, but still want the Cloudflare functions. With is preset you should be able to do either a SPA or SSR. nuxt build is for SSR and nuxt generate is for static/SPA. Currently it will not create the Cloudflare functions if you use nuxt generate
