升级后的Spring Boot版本从2.6.6到2.6.7，我得到下面的错误，而执行Web客户端的休息调用。
样本代码

public void execute(BiConsumer<ResponseEntity<JsonNode>, Throwable> responseConsumer) {
    WebClient.RequestBodyUriSpec uriSpec = getUriSpec();
    Mono<ResponseEntity<JsonNode>> responseEntityMono = uriSpec
            .uri(this::buildUri)//"localhost:1234")//
            .headers(this::setHeaders)
            .body(insertBody())
            .retrieve().onRawStatus(i -> i == 599,
            response -> response.bodyToMono(String.class)
                .map(body -> new ExternalException(599, body)))
            .toEntity(JsonNode.class);
    CompletableFuture<ResponseEntity<JsonNode>> completableFuture = responseEntityMono.toFuture();
    completableFuture.whenCompleteAsync(responseConsumer);
}
