Issue: Schema generation issue when using Prisma `@@id` attributes.

[robm94]

After adding a many to many relation I get the following error when running "npm run dev"

[vite-node] Failed to execute file:

The output of the schema.gpl file looks wrong it has a lot of indents and spaces that should not be there.
Here is the schema.prisma file I used.

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

generator client {
    provider      = "prisma-client-js"
    binaryTargets = ["native", "rhel-openssl-1.0.x"]
}

generator appsync {
    provider = "prisma-appsync"
}

model Post {
    id         Int                 @id @default(autoincrement())
    title      String
    categories CategoriesOnPosts[]
}

model Category {
    id    Int                 @id @default(autoincrement())
    name  String
    posts CategoriesOnPosts[]
}

model CategoriesOnPosts {
    post       Post     @relation(fields: [postId], references: [id])
    postId     Int // relation scalar field (used in the `@relation` attribute above)
    category   Category @relation(fields: [categoryId], references: [id])
    categoryId Int // relation scalar field (used in the `@relation` attribute above)
    assignedAt DateTime @default(now())
    assignedBy String

    @@id([postId, categoryId])
}

Thanks for reporting @robm94!

The issue seems related to @@id([postId, categoryId]) as replacing it with a classic id Int @id @default(autoincrement()) solves the issue.

Will look into it and hopefully ship a fix with the next release.

Fix released with 1.0.0-rc.7.
