retrieving EntryID for Checkbox item in Google Sheets Form not working - google-apps-script

Question

I used the code from #contributorpw on this post get Entry ID which is used to pre-populate fields (Items) in a Google Form URL and added the extended list of form types from #SourceFli (in same post).
I get the error message: "Exception: The parameters (String) don't match the method signature for FormApp.CheckboxItem.createResponse". That checkbox has only 1 option: "yes".
The rest of all my form items are only TEXT items and work fine.
function getPreFillEntriesMap(){
var ssOrder = SpreadsheetApp.openById(ORDER_SPREADSHEET_ID);
var orderFormUrl = ssOrder.getFormUrl();
var orderForm = FormApp.openByUrl(orderFormUrl);
var form = orderForm;
// var form = FormApp.openById(id);
var items = form.getItems();
var newFormResponse = form.createResponse();
var itms = [];
for(var i = 0; i < items.length; i++){
var response = getDefaultItemResponse_(items[i]);
if(response){
newFormResponse.withItemResponse(response);
itms.push({
id: items[i].getId(),
entry: null,
title: items[i].getTitle(),
type: "" + items[i].getType()
});
}
}
var ens = newFormResponse.toPrefilledUrl().split("&entry.").map(function(s){
return s.split("=")[0];
});
ens.shift();
return Logger.log(itms.map(function(r, i){
r.entry = this[i];
return r;
}, ens));
}
function getDefaultItemResponse_(item){
switch(item.getType()){
case FormApp.ItemType.TEXT:
return item.asTextItem().createResponse("1");
break;
case FormApp.ItemType.MULTIPLE_CHOICE:
return item.asMultipleChoiceItem()
.createResponse(item.asMultipleChoiceItem().getChoices()[0].getValue());
break;
case FormApp.ItemType.CHECKBOX:
return item.asCheckboxItem()
.createResponse(item.asCheckboxItem().getChoices()[0].getValue());
break;
case FormApp.ItemType.DATETIME:
return item.asDateTimeItem()
.createResponse(new Date());
break;
case FormApp.ItemType.DATE:
return item.asDateItem()
.createResponse(new Date());
break;
case FormApp.ItemType.LIST:
return item.asListItem()
.createResponse(item.asListItem().getChoices()[0].getValue());
break;
case FormApp.ItemType.PARAGRAPH_TEXT:
return item.asParagraphTextItem()
.createResponse(item.asParagraphTextItem().createResponse("some paragraph"));
break;
case FormApp.ItemType.CHECKBOX_GRID:
return item.asCheckboxGridItem()
.createResponse(item.asCheckboxGridItem().createResponse([item.asGridItem().getColumns[0], item.asGridItem().getRows[0]]));
break;
case FormApp.ItemType.DURATION:
return item.asDurationItem()
.createResponse(item.asDurationItem().createResponse(2, 20, 20));
break;
case FormApp.ItemType.GRID:
return item.asGridItem()
.createResponse(item.asGridItem().createResponse([item.asGridItem().getColumns[0], item.asGridItem().getRows[0]]));
break;
case FormApp.ItemType.SCALE:
return item.asScaleItem()
.createResponse(item.asScaleItem().createResponse(1));
break;
case FormApp.ItemType.TIME:
return item.asTimeItem()
.createResponse(item.asTimeItem().createResponse(1, 1));
break;
default:
return undefined;
}
}

Answer 1

response of createResponse(responses) of Class CheckboxItem is String[]. In your script, the string is used. I thought that this might be the reason of your issue. So how about the following modification?
From:
return item.asCheckboxItem()
.createResponse(item.asCheckboxItem().getChoices()[0].getValue());
To:
return item.asCheckboxItem()
.createResponse([item.asCheckboxItem().getChoices()[0].getValue()]);
Reference:
createResponse(responses)
