Google Apps Script Form textValidationBuilder does not recognize regex pattern - regex

Question

I am trying to create a Form with apps script and for some reason it will not allow the simplest phone number validation in a TextItem input field. I only need the user to enter their 10 digit number with no spaces, dashes, dots, with area code included. I know this isn't the technical "best" way to validate phone numbers but for our purposes it works. This is section of code I have to generate the field. (edited to make a more reproducible example)
function CreateForm() {
var form = FormApp.create('Test');
var tenantNum = form.addTextItem()
.setTitle("Tenant Phone #");
var phoneValid = FormApp.createTextValidation()
.setHelpText("Please enter valid phone number, 10-digits, no symbols or spaces.")
.requireTextMatchesPattern(/\d{10}/g)
.build();
tenantNum.setValidation(phoneValid);
console.log(form.getPublishedUrl())
}
I have also tried other things like:
(No capture group or global tag, both individually)
.requireTextMatchesPattern(/\d{10}/)
Entering the regex as a string literal.
.requireTextMatchesPattern("\d{10}")
Even dumdum stuff like.
.requireTextMatchesPattern(/[0-9]{10}/)
or
.requireTextMatchesPattern(/\d\d\d\d\d\d\d\d\d\d/)
Just to see if it works. I have also tried .requireTextContainsPattern() as well.
Whenever you enter in the form however i get this response:
Please enter valid phone number, 10-digits, no symbols or spaces.
My only thought is that there might be some confusion with whether or not the user is entering a string vs. number and this method only works on strings. But this validation
and regex work fine when you enter it into the form creation manually so I'm completely lost. Any help is appreciated!

Just a guess... Try this:
.requireTextMatchesPattern("\\d{10}")
Update
It works fine for me:
function CreateForm() {
var form = FormApp.create('Test');
var tenantNum = form.addTextItem()
.setTitle("Tenant Phone #");
var phoneValid = FormApp.createTextValidation()
.setHelpText("Please enter valid phone number, 10-digits, no symbols or spaces.")
.requireTextMatchesPattern("\\d{10}")
.build();
tenantNum.setValidation(phoneValid);
console.log(form.getPublishedUrl())
}
And the "not existed" method setHelpText() works fine as well, as you can tell from the screenshots.
