谷歌表单AppScript -项目选择在查看时消失，但它在编辑视图中显示？

Question

我创建了一个附加组件，用于在表单中将问题和选择作为多选项导入。

问题、答案和正确答案完全导入，并在编辑视图中按预期显示，但在预览表单/测验时，某些问题缺少选项。

有什么想法吗？

function createMCQ(k) {
  var form = FormApp.getActiveForm();
  form.setIsQuiz(true)
  .setShuffleQuestions(true)
  .setAllowResponseEdits(false)
  .setLimitOneResponsePerUser(false)
  .setCollectEmail(true)
  .setShowLinkToRespondAgain(false);
  
  
  for (var i = 0, len = k.length; i < len; i++) {
    var item = form.addMultipleChoiceItem();
    item.setTitle(k[i].question)
    .setPoints('1')
    .setRequired(true)
    .setChoices([
    item.createChoice(String(k[i].a), Boolean(k[i].answer =='A')),
    item.createChoice(String(k[i].b), Boolean(k[i].answer =='B')),
    item.createChoice(String(k[i].c), Boolean(k[i].answer =='C')),
    item.createChoice(String(k[i].d), Boolean(k[i].answer =='D')),
    ]);
  }
}

它是从对象导入的，如下所示；

"questions": [
    {
      "course": "GCSE AQA Biology",
      "question": "State the equation that links magnification, image size and actual size.",
      "a": "Actual Size = Image Size / Magnification",
      "b": "Actual Size = Magnification / Image Size",
      "c": "Actual Size = Resolution / Magnification",
      "d": "Resolution = Image Size / Magnification",
      "topic": "Cells",
      "answer": "A",
      "id": 2
    },
    {
      "course": "GCSE AQA Biology",
      "question": "Which type of microscope has higher magnification and resolving power?",
      "a": "Light Microscopes",
      "b": "Magnifying Glass",
      "c": "Super Microscope",
      "d": "Electron microscopes",
      "topic": "Cells",
      "answer": "D",
      "id": 3
    }
]

项目完全导入，编辑时如图所示：

但是，在预览表单时，其中一些选项会丢失：

这是非常随机的，即不是孤立于某些问题。

任何建议都将不胜感激！

Answer 1

我想我已经修好了(?)这个；

在添加多项选择项时，我首先添加了选项，然后再添加任何其他属性：

k.map(e => {
    var item = form.addMultipleChoiceItem();
    item.setTitle(e.question)
    .setChoices([
    item.createChoice(String(e.a), Boolean(e.answer =='A')),
    item.createChoice(String(e.b), Boolean(e.answer =='B')),
    item.createChoice(String(e.c), Boolean(e.answer =='C')),
    item.createChoice(String(e.d), Boolean(e.answer =='D')),
    ])
    .setPoints('1')
    .setRequired(true);
})

使用map而不是for与tho无关。

我做了一些测试，看起来答案选择不再消失了。祈祷吧！可能是Google的bug？
