Shared types in GraphQL Federation (@shareable)

Hi again,

So you can confirm that your only two subgraphs are

Shows:

type Query @extends{
    shows(titleFilter: String): [Show]
}

type Show @key(fields: "id") {
    id: ID
    title: String
    releaseYear: Int
}

Reviews:

type Show @key(fields: "id") @extends {
    id: ID @external
    reviews: [Review]
}

type Review {
    starRating: Int
}

Appearing exactly as above (updated with the changes applied/saved), and the supergraph is an attempted federation of these two subgraphs? And the error remains the same; i.e., “Supergraph schema validation failed: ‘there can be only one query type in schema’”?

Thanks for your patience and assistance on this.

David
