Prisma 6.16.0 types issue with prisma-client generator

[mhodgson]

With the move to 6.16.0 the files in the generated Prisma Client models folder now use import type * as runtime from "@prisma/client/runtime/library" instead of import * as runtime from "@prisma/client/runtime/library". In the modified Zenstack version of these files we prepend import $Types = runtime.Types (unclear why this is needed). This now raises the following type error:

error TS1380: An import alias cannot reference a declaration that was imported using 'import type'.

I'd make a fix for this but I'm unclear if this import declaration is really needed or what purpose it serves.

Environment:

• ZenStack version: 2.18.1
• Prisma version: 6.16.0
• Database type: Postgresql

Hi @mhodgson , thanks for reporting this.

The "$Types" import was for supporting using "Prisma.skip" for optional JSON fields. You'll see the use of it with:

type Profile {
  age Int
}

model User {
  id      Int      @id @default(autoincrement())
  email   String   @unique
  profile Profile? @json
}

I think a simple fix would be just get rid of the "import $Types = runtime.Types", and change code generation of "$Types" to "runtime.Types.Skip". It should work for both the old and new Prisma generator I believe.
