我刚开始使用 gApps 脚本，在尝试设置我的 UI 以在处理任务时禁用提交按钮时，我的代码（如下）遇到了两个问题。

  1. 尝试加载脚本时，我偶尔会收到以下错误：“遇到错误：发生意外错误”。这个错误是不一致的，因为我需要做的就是刷新脚本，然后它会为我加载。当我根本没有更改代码时，它有时有效，有时无效，这真的让我很困扰。

  2. 当最后第三行//button_submit.setEnabled(true);未注释时，每次我尝试加载脚本时都会发生错误。

在试图找出问题所在时，我注意到 getElementById() 似乎没有为提交按钮分配正确的 UI 类型。我不确定这是否是问题的原因，但我怀疑这与我在测试脚本中看到的相同行为不同，我为查看是否可以从更简单的基础复制问题。

如果您对导致此问题的原因提供任何反馈，我将不胜感激。

谢谢

分而治之——

我有几次这个错误，我能找到原因的唯一方法是“分而治之”。

...

因为我知道...

A) 相同的对象 ID 用于不同类型的对象，即使旧对象已被移除。

B) 无效的颜色值

C) 使用 createApplication 两次创建应用程序对象

The error looks to be a kind of catch all error message. It also looks to be a client side error, so not sure logging will help.
