Я хочу визуализировать страницу ejs в экспресс (eureka-client) из службы весенней загрузки (rest controller) (eureka-client) через feign

Question

// форма в файле ejs в экспресс-приложении для добавления pacient и отправки данных в службу остальной загрузки весеннего использования бросить zuul api gateway

 <form class="form-horizontal form-label-left"  method="post" th:action="@{/http://localhost:8080/pacient-service/addPacient}" action="http://localhost:8080/pacient-service/addPacient" th:object="${pacient}" novalidate>

// контроллер в pacient service (весенняя загрузка)

@RestController
public class PacientController {

    @Autowired
    private PacientRepository pacientRepository;
    @Autowired
    private ClientAppServiceProxy clientAppServiceProxy;
    @GetMapping("/pacient")
    @ResponseBody
    public String getTest(){
        return "hello from pacient" ;
    }

    @GetMapping("/pacients")
    public List<Pacient> getPacients(){
        return pacientRepository.findAll();
    }

    @PostMapping("/addPacient")
    public void addPacient(@ModelAttribute("pacient") Pacient pacient, @RequestParam("datalindjes") String s){
        Date datalindjes = null;
        try {
             datalindjes=new SimpleDateFormat("yyyy-MM-dd").parse(s);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        pacient.setDataLindes(datalindjes);
        System.out.println("---------------------"+s.toString());
        System.out.println(pacient.getDataLindjes());
      pacientRepository.save(pacient);
           **clientAppServiceProxy.showPacients();  <<--**  //want to render ejs page in express app (client)
    }

// служба клиентского приложения симулирует прокси в pacient service

@FeignClient(name="zuul-api-gateway")
@RibbonClient(name="client-app-node")
public interface ClientAppServiceProxy {

    @GetMapping("/client-app-node/pacients")
    void showPacients();
}

// отображает страницу пациентов в экспресс-клиенте

app.get("/pacients",function(req,res){
    res.render("/pacientet") // ejs file to show pacients
})

// pacient service (весенняя загрузка)выдает ошибку:
