    execute(namingService, service -> {
        listener.getServiceNames().forEach(serviceName -> {
            try {
                service.subscribe(serviceName, e -> {
                    // Register Nacos EventListener
                    if (e instanceof NamingEvent) {
                        NamingEvent event = (NamingEvent) e;
                        handleEvent(event, listener);

                if (isServiceNamesWithCompatibleMode(url)) {
                    // Get all instances with corresponding serviceNames to avoid instance overwrite and but with empty instance mentioned
                    // in https://github.com/apache/dubbo/issues/5885 and https://github.com/apache/dubbo/issues/5899
