Issue with Reactive Streams Wrapper code

[RonyOCuinn]

The example code given here for ExampleReactor does not compile.

The code in question:

public interface GitHubReactor {
      
  @RequestLine("GET /repos/{owner}/{repo}/contributors")
  Flux<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo);
  
  class Contributor {
    String login;
    
    public Contributor(String login) {
      this.login = login;
    }
  }
}

public class ExampleReactor {
  public static void main(String args[]) {
    GitHubReactor gitHub = ReactorFeign.builder()      
      .target(GitHubReactor.class, "https://api.github.com");
    
    List<Contributor> contributors = gitHub.contributors("OpenFeign", "feign")
      .map(Contributor::new)
      .collect(Collectors.toList())
      .block();
  }
}

Gives the error:

Error:(31, 17) java: method map in class reactor.core.publisher.Flux<T> cannot be applied to given types;
  required: java.util.function.Function<? super com.example.spring.demo.GitHubReactor.Contributor,? extends V>
