After searching I found the differences needed to achieve the error. I have made a public repo for you to check, download it make a .env with SESSION_SECRET_KEY and a mysql db url, and run it with pnpm vercel deploy. In the last commit it errors as I said, in the commit before that, named "works" it works.

TLDR: Next 14 instead of 13 breaks it

With #4311, next 14 works for me. Maybe you can try different deploy platform like flightcontrol or railway
