Стандарт Google Appengine: Java8 Настройка конечных точек с помощью IAP и ESP

Question

Я работаю над веб-приложением, которое работает в Google Appengine и к которому можно получить доступ из приложения Android, которое синхронизирует некоторые данные с сервера. У меня это работало гладко до недавнего времени, когда я воссоздал проект на GCP и настроил IAP, который отлично работает.

Однако я не могу настроить конечную точку, где я продолжаю получать 500 Ошибка сервера . Я выполнил каждый шаг в этой онлайн-инструкции от Google https://cloud.google.com/endpoints/docs/openapi/get-started-app-engine-standard и не могу понять, что я делаю не так !!

Вот содержимое моих файлов:

Эхо. java

package com.example.endpoints;
import ...
@Api(
        name = "echo", 
        version = "v1",
        clientIds = { IAP_CREATED_WEBCLIENTID_FROM_CREDENTIALS, Constant.API_EXPLORER_CLIENT_ID},
        audiences = {IAP_CREATED_WEBCLIENTID_FROM_CREDENTIALS}, 
        namespace = @ApiNamespace(
                ownerDomain = "com.example.endpoints", 
                ownerName = "com.example.endpoints", 
                packagePath = "")
)

public class Echo {

  @ApiMethod(name = "echoonly", path = "/echo/v1/echoonly")
  public Entity echoonly() {      
    Entity testingResponse = new Entity("TestingResponse", 1000000L);
    testingResponse.setProperty("name", "Only");
    return testingResponse;
  }

  @ApiMethod(name = "echoname", path = "/echo/v1/echoname/{name}")
  public Entity echoname(
        @Named("name") @Nullable String name) {     
    Entity testingResponse = new Entity("TestingResponse", 1000000L);
    testingResponse.setProperty("name", name);
    return testingResponse;
  }

  @ApiMethod(name = "echoage", path = "/echo/v1/echoage/{name}/{age}")
  public Entity echoage(
        @Named("name") String name, 
        @Named("age") String age) {     
    Entity testingResponse = new Entity("TestingResponse", 1000000L);
    testingResponse.setProperty("name", name);
    testingResponse.setProperty("age", age);        
    return testingResponse;     
  }
}

Update Я не мог понять этого и пошел с Spring @RestController, который работал идеально, не беспокоясь о создании API конечных точек на Google Cloud Platform
