jdk:17 springboot:2.7.2 springcloud:2021.0.3 Here is my sample code

@RestController
@RequestMapping("user")
@RequiredArgsConstructor
public class UserController {

    private final UserRemoteService userRemoteService;

    @GetMapping
    public void users() {
        feign();
    }

    @Async
    public void feign() {
        userRemoteService.users()
                .forEach(System.out::println);
    }
}

@FeignClient(contextId = "userRemoteService", value = "feign-provider-biz",
        fallbackFactory = UserRemoteServiceFallbackFactory.class)
public interface UserRemoteService {

    @Cacheable(value = "users", key = "'user:all'", unless = "#result.empty")
    @GetMapping("/users")
    List<Users> users();
}

This is the resulting exception message

Hello, @livk-cloud , please provide a minimal, complete, verifiable example that reproduces the issue, as a link to a small project with executable class/ tests and not as code snippets that require additional setup on our side.

openfeign-demo.zip Please read the README

Thanks for the sample @livk-cloud. I was able to reproduce it.

@OlgaMaciaszek Any update on this fix? I am also facing the similar issue we are not able to make a Call using Aysnc annotation

Hello @bsudabathula9 not yet, have been mostly focused on adding features to Spring Interface Clients for the new Framework release. Will post all relevant updates here.

OlgaMaciaszek avatar Aug 17 '23 11:08 OlgaMaciaszek

@OlgaMaciaszek, any updates on this?

@mariusingjer, unfortunately not yet; we're sorry for the delay on this. SC OF issues now have a lower priority as we recommend migrating over to Spring Interface Clients; we have this in the backlog and will get to it as soon as higher-priority issues are handled.
