Can't delete nodes of types that lack the id field

[marktani]

1. Deploy a service with this datamodel:

type WithoutId {
  string: String @unique
}

2. Create a node of type WithoutId.
3. Try to delete the node from the UI - you'll get this error:

"message": "Argument 'where' expected type 'WithoutIdWhereUniqueInput!' but got: {id: $id}. Reason: 'id' Field 'id' is not defined in the input type 'WithoutIdWhereUniqueInput'. (line 2, column 30):\n      deleteWithoutId(where: {id: $id}) {\n                             ^\n (line 2, column 31):\n      deleteWithoutId(where: {id: $id}) {\n                              ^",

    {

      "column": 31
    }
  ]
}
