ConnectorError { user_facing_error: None, kind: ForeignKeyConstraintViolation }

I'm on the latest alpha branch, this is my schema:

datasource db {
  provider = "sqlite"
  url      = "file:./dev.db"
}

generator client {
  provider = "prisma-client-js"
}

model Post {
  title     String  @unique
  content   String?
  published Boolean @default(false)
  author    User?
}

model User {
  email String  @unique
  name  String?
  posts Post[]
}

I migrated it using prisma2 migrate and now want to use Prisma Client like so:

const user = await prisma.user.create({
  data: {
    email: "[e-mail]",
    posts: {
      create: {
        title: "Hello"
      }
    }
  }
})

When running this code, I'm getting this error:

$ yarn dev
yarn run v1.22.0
$ ts-node ./script.ts
(node:46967) UnhandledPromiseRejectionWarning: Error: 
Invalid `prisma.users.create()` invocation:

Is this a bug or am I doing something wrong?

Actually this was my bad, I messed up the client generation somehow... after deleting and re-generating this worked 🎉

Thanks @nikolasburk !
