尝试在 Google 表单上预先填写复选框答案，但不起作用

Question

Using the solution provided here , I am trying to pre-fill and submit a Google Form. It works until it gets to a checkbox question - for example:

Question on form: Has this topic been discussed with someone? Possible answers: John, Harry, Alice

The answer I am attempting to pre-fill is "Alice" - but I receive the error message below:

Exception: The parameters (String) don't match the method signature for FormApp.CheckboxItem.createResponse. See code below. Any help is appreciated...

Try this:

function dataFromGSheets() {
  const ss = SpreadsheetApp.getActive();
  const sheet = ss.getSheetByName("Sheet1");
  const [header, ...data] = sheet.getDataRange().getDisplayValues();
  const choices = {};
  header.forEach((title, index) => {
   choices[title] = data.map(row => row[index]).filter(e => e) });
  return choices;
}

function populateGForms() {
  const Google_Form_ID = gobj.globals.editformid2;
  const googleForm = FormApp.openById(Google_Form_ID);
  const items = googleForm.getItems();
  const choices = getDataFromGoogleSheets();
  items.forEach(function (item) {
    const itemTitle = item.getTitle();
    if (itemTitle in choices) {
      const itemType = item.getType();
      switch (itemType) {
        case FormApp.ItemType.CHECKBOX:
          item.asCheckboxItem().setChoiceValues([...new Set(choices[itemTitle])]);
          break;
        case FormApp.ItemType.LIST:
          item.asListItem().setChoiceValues([...new Set(choices[itemTitle])]);
          break;
        case FormApp.ItemType.MULTIPLE_CHOICE:
          item.asMultipleChoiceItem().setChoiceValues([...new Set(choices[itemTitle])]);
          break;
        default:
          Logger.log("Ignore question", itemTitle);
      }
    }
  });
}
