google-apps-script - 不支持 SpreadsheetApp.getUi() 操作？

Question

试图在用户单击菜单项时添加确认对话框，我几乎完全按照这个 Google 页面进行操作:https://developers.google.com/apps-script/guides/dialogs#alert_dialogs

但是，我收到“不支持此操作”的错误消息。在执行记录中，我看到了这个:

[14-02-10 12:21:54:551 EST] Starting execution
[14-02-10 12:21:55:550 EST] Execution failed: This operation is not supported (line 28, file "Code") [0.226 seconds total runtime]

“代码”中的第28行是下面函数的第二行:

function sendMergedMail() {
  var ui = SpreadsheetApp.getUi();
  var result = ui.alert(
     'Please confirm',
     'Are you sure you want to continue?',
      ui.ButtonSet.YES_NO);
  if (result != ui.Button.YES) {
    return
  }

  var doc = SpreadsheetApp.getActiveSpreadsheet();
  doc.toast("Current sheet: "+doc.getName());
};

谢谢!

此代码适用于 new version of spreadsheets ，你升级到新版本了吗？

(刚刚测试，没有问题)
