How do i change/update validation of question (item) in google form with apps scripts

问题

I have already try to update text validation for my class with google apps scripts but it say "textItem.setValidation is not a function". Please help me

function setPass() {
var form = FormApp.openById('Google Form ID');
var textItem = form.getItemById(Question ID);
var textValidation = FormApp.createTextValidation()
.requireNumberEqualTo(22111)
.build();
textItem.setValidation(textValidation)

You are very close to update the question, you only need to add the method .asTextItem() after getting the item by id. The final code should look like this:

function setPass() {
var form = FormApp.openById('Google Form ID');
var textItem = form.getItemById(Question ID).asTextItem();
var textValidation = FormApp.createTextValidation()
.requireNumberEqualTo(22111)
.build();
textItem.setValidation(textValidation)

Don't hesitate to ask me any question if you need further help.
