Error Running sample GraphQL query on Books with Authors

Hello, I was re-testing the Cosmos Starter doc GraphQL queries (dab updated to latest 0.2.52 version) based on https://github.com/Azure/data-api-builder/blob/main/docs/getting-started/getting-started-azure-cosmos-db.md#graphql-operations-on-entity-relationships and found that while simple GraphQL query on single entity worked fine, query on multiple entity/types from that Doc example (Books and Authors) failed with Type error - See below.

 {
    "errors": [
        {
            "message": "The field `authors` does not exist on the type `Book`.",
            "locations": [
                {
                    "line": 7,
                    "column": 7
                }
            ],
            "path": [
                "books",
                "items"
            ],
            "extensions": {
                "type": "Book",
                "field": "authors",
                "responseName": "authors",
                "specifiedBy": "http://spec.graphql.org/October2021/#sec-Field-Selections-on-Objects-Interfaces-and-Unions-Types"
            }
        }
    ]
}
