Custom primary key @primaryKey doesn’t work with @auth

[stephenjen]

Description

I have two parent / child tables, and the parent table has custom primary key:

type Book @model @auth(rules: [{ allow: private, ownerField: "pOwner" }]) {
  id: ID! @primaryKey(sortKeyFields: ["title", "description"])
  title: String!
  description: String!
  writers: [Writer] @hasMany(indexName: "byBook", fields: ["id"])
  pOwner: String!
}

type Writer @model {
  id: ID!
  fname: String!
  lname: String!
  bookID: ID! @index(name: "byBook", sortKeyFields: ["id"])
  book: Book! @belongsTo(fields: ["bookID"])
  pOwner: String!
}

When I add the same @auth to the child, I get the following error on attempt to generate the model with 'amplify codegen models':

InvalidDirectiveError: Invalid @belongsTo on Writer:book. Provided fields do not match the size of primary key(s) for Book

Below are the models that cause this error:

type Book @model @auth(rules: [{ allow: private, ownerField: "pOwner" }]) {
  id: ID! @primaryKey(sortKeyFields: ["title", "description"])
  title: String!
  description: String!
  writers: [Writer] @hasMany(indexName: "byBook", fields: ["id"])
  pOwner: String!
}

type Writer @model @auth(rules: [{ allow: private, ownerField: "pOwner" }]) {
  id: ID!
  fname: String!
  lname: String!
  bookID: ID! @index(name: "byBook", sortKeyFields: ["id"])
  book: Book! @belongsTo(fields: ["bookID"])
  pOwner: String!
}
