Vercel deploy fails

[proton1k]

Hi,
this is the error in logs on deploy on Vercel:

Error:
--
21:01:42.712 | You don't have any models defined in your schema.prisma, so nothing will be generated.
21:01:42.712 | You can define a model like this:
21:01:42.712 |  
21:01:42.712 | model User {
21:01:42.712 | id    Int     @id @default(autoincrement())
21:01:42.712 | email String  @unique
21:01:42.713 | name  String?
21:01:42.713 | }

Previous error was due to wrong prisma configuration: inability to parse the db config which has to start with "file:" ... 🤔❓

I've added all possibly necessary environment variables from .env but can't get pass it. The RedwoodJS documentations also says nothing about this, only "success path", no troubleshooting notes.

Do you have any idea why, what's wrong? The code is literally the same from this repo plus from the article on Supabase pages.
