为使用Google帐户在Meteor应用程序上注册的用户处理Google日历数据？

如何为在Meteor应用程序中使用Google帐户注册的用户处理Google日历数据？

例如，我要插入事件或至少发送事件邀请。我的用户使用Google帐户在我的应用程序中注册，但是即使他们注销了，我也想插入事件。下面是我到目前为止拥有的服务器代码，但是它给了我“权限不足”错误。

  if (user && user.services && user.services.google && 
        user.services.google.accessToken) {
    var startTimeUTC = moment.utc(event.startTime, "YYYY-MM-DD HH:mm:ss").format();
    var endTimeUTC = moment.utc(event.endTime, "YYYY-MM-DD HH:mm:ss").format();
    console.log("POSTINGGCAL");
    if (moment.utc().unix() < moment.utc(event.endTime).unix()) {
      console.log("ENTERGCAL");
      var id = Meteor.http.post("https://www.googleapis.com/calendar/v3/calendars/primary/events", {
        'headers' : { 
          'Authorization': "Bearer " + user.services.google.accessToken,
          'Content-Type': 'application/json' 
        },
        'data': {
          "summary": event.name,
          "location": event.location,
          "start": {
            "dateTime": startTimeUTC,
          },
          "end": {
            "dateTime": endTimeUTC,
          },
          "attendees": [
            {
              "email": user.email,
            },
          ]          
        }
      });
    }//end if moment
  }//end if user

编辑：我在客户端上添加了以下内容，尽管我不再收到任何错误，但日历事件未显示在我的测试Google帐户上。有任何想法吗？

Accounts.ui.config({
    requestPermissions: {
        google: 
        ['https://www.googleapis.com/auth/calendar',
        'https://www.googleapis.com/auth/calendar.readonly',
        'https://www.googleapis.com/auth/userinfo.profile',
        'https://www.googleapis.com/auth/userinfo.email',
        'https://www.googleapis.com/auth/tasks'],
//      forceApprovalPrompt: {google: true}
    }, 
    forceApprovalPrompt: {google: true},
    requestOfflineToken: {google: true},
    passwordSignupFields: 'EMAIL_ONLY',
//      extraSignupFields: []
});

以下流星文档无济于事，因为出现此错误：未捕获的错误：Accounts.ui.config：无效的密钥：forceApprovalPrompt
