Address lenght condition not working

Summary:

Hello,

I'm trying to restrict the character lenght to 10 for one of the address field, in the address section.

I created an advanced expression but this one is not triggering any error message when I'm testing. Below the expression:

function runCondition(context) {
const { $componentContext, $fields, $modules, $user } = context;

  if (((($componentContext.Country.includes('Germany') || $componentContext.Country.includes('Austria'))))) {

  return true;

  }

const AddressLine3 = $fields.personAddressAll.AddressLine3.$value();

const regexp = new RegEx("^[a-zA-Z0-9]{1,10}$","");

const AddressLine3Check = regexp.test(AddressLine3);

if (AddressLine3Check === false) {

  return true;

}

return false;

I followed the same steps as I saw in a demo, but I don't have the expected behavior
