I have a spring-boot graphQL SPQR service exposing a subgraph.
We are using apollo server for federation of all subgraphs into a super graph.
To make the subgraph schema federation compatible, apollo has a project called federation-jvm
Their SchemaTransformer adds common Federation type definitions (e.g. _Any scalar, _Entity union, Federation directives, etc).

From their examples, I noticed I had to add the below two beans to spring application.

@Bean
public GraphQlSourceBuilderCustomizer customizer(FederationSchemaFactory factory) {
    return builder -> builder.schemaFactory(factory::createGraphQLSchema);
}

@Bean
FederationSchemaFactory federationSchemaFactory() {
    return new FederationSchemaFactory();
}

That fails with error “No GraphQL schema definition was configured” because a schema definition is expected.

Here’s the full stack trace. Please give me some pointers how I can integrate their Schema transformer.
