how to map a list of fields via this library

[bbakerman]

I was testing out this library via the Spotify test API : https://spotify-graphql-server.herokuapp.com/graphql

The query would be

query ($byName: String) {
  queryArtists(byName: $byName) {
    image
    albums {
      image
      name
      id
      tracks {
        preview_url
        name
        id
      }
    }
    name
    id
  }
}

with variables byName : "Red Hot Chili Peppers"

Debugging shows it sending the right query and data back but it fails to Deserliase into a structure

Exception in thread "main" GraphQLException{message='OK', status='200', description='Unrecognized field "queryArtists" (class com.atlassian.model.Query), not marked as ignorable (0 known properties: ])

    at io.aexp.nodes.graphql.GraphQLTemplate.query(GraphQLTemplate.java:58)
    at com.atlassian.Main.main(Main.java:23)

My code is this

public static void main(String[] args) throws MalformedURLException {
        GraphQLTemplate graphQLTemplate = new GraphQLTemplate();

        GraphQLRequestEntity requestEntity = GraphQLRequestEntity.Builder()
                .url("https://spotify-graphql-server.herokuapp.com/graphql")
                .variables(new Variable("byName", "Red Hot Chili Peppers"))
                .scalars(BigDecimal.class)
                .request(Query.class)
                .build();
        GraphQLResponseEntity<Query> responseEntity = graphQLTemplate.query(requestEntity, Query.class);
        System.out.println(responseEntity);
    }

My model classes are

public class Query {

    @GraphQLVariable(name = "byName", scalar = "String")
    List<Artist> queryArtists;
}

public class Artist {
    String name;
    String id;
    String image;
    List<Album> albums;
}

public class Album {
    String name;
    String id;
    String image;
    //List<Track> tracks;
}

public class Track {
    String name;
    //List<Artist> artists;
    String preview_url;
    String id;
}

I guess I am unsure about where the entry point for queries are. The samples in the library only every enter a single value field (eg User via github /user) and not a list field like above

Am I off track on how this gets set up?

ps. I am one of the maintainers of graphql-java so my server side graphql knowlege is ok but I am trying to work out this as a client side consumer library

[bbakerman]

Ahh worked it out just after I typed all this

The model classes MUST be public. So

public class Query {

    @GraphQLVariable(name = "byName", scalar = "String")
    public List<Artist> queryArtists;
}
