I’m making multiple API calls at the same time with CompletableFuture to reduce user waiting time.
Here is my code:

@Async
    public CompletableFuture<CommonDataDTO> commonData() throws JsonProcessingException, ExecutionException, InterruptedException {
        CompletableFuture<UserDTO[]> completableFutureUser = CompletableFuture.supplyAsync(() -> {
            try {
                return  apiHelper.getEmployee();
            } catch (JsonProcessingException e) {
                return new UserDTO[0];
            }
        });
        CompletableFuture<ContactDTO[]> completableFutureContact = CompletableFuture.supplyAsync(() -> {
            try {
                return  apiHelper.getTravelAgent();
            } catch (JsonProcessingException e) {
                return new ContactDTO[0];
            }
        });
        CompletableFuture<CurrencyRateDTO[]> completableFutureCurrency = CompletableFuture.supplyAsync(() -> apiHelper.getCurrencyRate("site"));

        return CompletableFuture.allOf(completableFutureUser, completableFutureContact, completableFutureCurrency).thenApply(v -> {
            return new CommonDataDTO(Arrays.stream(completableFutureUser.join()).toList(), Arrays.stream(completableFutureContact.join()).toList(), Arrays.stream(completableFutureCurrency.join()).toList());
        });
    }

But when I run the above code I get an error message like:

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

I added @EnableAsync to the Application class.

Am I doing something wrong here?
Many thanks

I tried replacing allOf with thenCompine but everything is still the same
