NullConstraintViolation

I have the following models (simplified for reporting the issue):

model User {
  id         String        @default(cuid()) @id @unique
  email      String        @unique
  staff      Staff?
}

model Staff {
  id        String   @default(cuid()) @id @unique
  user      User
  active    Boolean?
}

When trying to add a user with the following query

mutation {
  createOneUser (data: {
    email: "[e-mail]"
  }) {
    id
    email
  }
}

I get the following error

"error": "ConnectorError(NullConstraintViolation { field_name: \"User.staff\" })"

This seems odd, since the staff field in the User model is optional. I have other 1-1 relations with the same problem.

Thanks, I can confirm all of this. Most of them related to the query engine so I am going to transfer this issue.

I can no longer reproduce any of these conditions now with prisma2@2.0.0-preview-5, binary version: 29f6d9f7f6d0a85cc30df1809733612bab56a1c5

These have been fixed between the updates
