使用Google Domain API 404 Not Found创建圈子

我正在尝试在用户的Google帐户中创建一个Circle . 我按照快速启动（https://developers.google.com/+/domains/quickstart/java）配置服务帐户及其凭据，并将域范围的权限委派给服务帐户 . 当我运行代码时，我得到了404 Not found响应 .

这是我的代码：

package com.google.plus.samples.quickstart.domains;

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;

import com.google.api.services.plusDomains.model.Circle;

public class DomainDelegation {
private static final String SERVICE_ACCOUNT_EMAIL = "serviceaccountemail@developer.gserviceaccount.com";
private static final String SERVICE_ACCOUNT_PKCS12_FILE_PATH =
  "privatekeypath.p12";
private static final String USER_EMAIL = "user1@mygoogledomain.com";
private static final List<String> SCOPE = Arrays.asList(
  "https://www.googleapis.com/auth/plus.me",
  "https://www.googleapis.com/auth/plus.stream.write",
  "https://www.googleapis.com/auth/plus.circles.read",
    "https://www.googleapis.com/auth/plus.circles.write",
    "https://www.googleapis.com/auth/plus.login");

private static PlusDomains authenticate() throws GeneralSecurityException, IOException {

System.out.println(String.format("Authenticate the domain for %s", USER_EMAIL));

HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();

GoogleCredential credential = new GoogleCredential.Builder()
    .setTransport(httpTransport)
    .setJsonFactory(jsonFactory)
    .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
    .setServiceAccountScopes(SCOPE)
    .setServiceAccountUser(USER_EMAIL)
    .setServiceAccountPrivateKeyFromP12File(
        new java.io.File(SERVICE_ACCOUNT_PKCS12_FILE_PATH))
    .build();

// Create and return the Plus service object
PlusDomains service = new PlusDomains.Builder(httpTransport, jsonFactory, credential)
    .setApplicationName("Test")
    .setHttpRequestInitializer(credential).build();
return service;
}

public static void main(String[] args) throws Exception {
// Create an authorized API client
PlusDomains service = authenticate();

Circle circle = new Circle();
circle.setDisplayName("Tech support");
Circle result = service.circles().insert("me", circle).execute();

System.out.println("Created 'Tech support' circle with id: " + result.getId());
  }
}

以下是我得到的回复：
