kit: @sveltejs/adapter-vercel not working anymore at vercel.com

Describe the bug

I have several SvelteKit websites hosted at vercel.com using @sveltejs/adapter-vercel. Since today (30/12/2021) deploys are not working anymore. If you run “npm run build” locally it works fine. Not on vercel itself.

Reproduction

Try to deploy on vercel.
