大家好，我现在在Node.js环境里对接Google Ads API，OAuth2授权环节明明走通了，但调用listAccessibleCustomers方法时直接卡壳，最后一条日志完全打不出来，还报了一堆gRPC相关的错误，实在摸不着头脑，想请各位帮忙排查下问题😭

核心代码片段： #

const { clientId, userId } = JSON.parse(state);
const oauth2Client = new google.auth.OAuth2(
  GOOGLE_CLIENT_ID.value(),
  GOOGLE_CLIENT_SECRET.value(),
  REDIRECT_URI.value()
);
const { tokens } = await oauth2Client.getToken(code);
console.log("OAuth Tokens: ", tokens);

const adsApi = new GoogleAdsApi({
  client_id: GOOGLE_CLIENT_ID.value(),
  client_secret: GOOGLE_CLIENT_SECRET.value(),
  developer_token: GOOGLE_ADS_DEVELOPER_TOKEN.value(),
  refresh_token: tokens.refresh_token,
});
console.log("Google Ads API initialized: ", adsApi);

// 就是这行调用触发了错误
const accessibleResourceNames = await adsApi.listAccessibleCustomers({
  refresh_token: tokens.refresh_token,
});
console.log("Accessible Resource Names: ", accessibleResourceNames);

完整报错信息： #

我已经排查过的点： #

• OAuth授权环节完全正常，能拿到有效的refresh_token，日志里能看到完整的token信息
• Client ID和Client Secret都是从Google Cloud控制台直接复制的，确认没有拼写错误
• 关于developer_token，我试过两种值：一种是去掉横杠的MCC账号ID（比如把111-111-1111改成1111111111），另一种是Google Ads账号API页面里显示的官方开发者令牌，但两种情况都报同样的错误

有没有朋友遇到过类似的问题？或者能帮我分析下这个invalid_request到底指向哪里的请求无效？万分感谢！
