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. Repo: https://github.com/cfragkos/blitz-test TLDR: Next 14 instead of 13 breaks it

With https://github.com/blitz-js/blitz/pull/4311, next 14 works for me. Maybe you can try different deploy platform like flightcontrol or railway

@siddhsuresh @flybayer any updates on this?

[siddhsuresh]

@cfragkos does version 2.0.6 fix this for you?

[cfragkos]

no

[cfragkos]

@siddhsuresh any updates?

[flybayer]

@cfragkos no, unfortunately we are unable to reproduce locally. This is a Vercel specific problem, and because they have lack of documentation, we are unable to investigate.

I recommend opening a Vercel support issue.
