Google Apps腳本：安排約會時的授權錯誤

Question

當我運行代碼時，它向我詢問授權/許可。我給了必要的權限並再次運行代碼。這一次，我得到了用戶界面。但是，當我按下提交按鈕我得到一個錯誤信息說，允許有必要執行此操作：

我怎樣才能解決呢？這段代碼（根據original google developers site在7月23日更新）過時了嗎？

function scheduleAppointment() { 
    var app = UiApp.createApplication().setTitle('Schedule an Appointment'); 
    var doc = SpreadsheetApp.getActiveSpreadsheet();

同樣從調試器運行調度功能。天然氣可能無法檢測到另一臺儀器的所有凝膠示波器。 如果它仍然不能工作寫一個函數，調用它調度好params，以便它實際上從調試器創建一個事件。

您可以嘗試撤銷腳本授權並重新授權，在初始授權過程中可能出現錯誤。

有關如何撤銷所有授權是指this other post顯示多種方式做到這一點跡象..
