Files not generated with Preview-Feature prismaSchemaFolder

[timreibe]

Bug description

I'm using the Preview-Feature prismaSchemaFolder to have multiple schema files in dictionary prisma/schema.

However, when I run npx prisma generate, the output folder for the zod-files is created, but is empty.

How to reproduce

1. Create directory prisma/schema
2. Create schema.prisma file with following content:

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["prismaSchemaFolder"]
}

generator zod {
  provider          = "prisma-zod-generator"
  output            = "./generated-zod-schemas"
  isGenerateSelect  = true
  isGenerateInclude = true
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  posts Post[]
}

model Post {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  title     String
  content   String?
  published Boolean  @default(false)
  viewCount Int      @default(0)
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  Int?
  likes     BigInt
}

3. run npx prisma generate
4. folder generated-zod-schemas was created but is empty

Expected behavior

I'd expect the zod-files to be created.

The exact same prisma.schema file works without previewFeature flag prismaSchemaFolder

it seems like any previewFeature has the same behavior; Here I have:
previewFeatures = ["relationJoins"]
