I have one function that uses the “Zend_Validate” Now I upgraded my Magento version to 2.4.6 and I got an error like..
with class replace
my code is
if (!Zend_Validate::is($email, MagentoFrameworkValidatorEmailAddress::class)) {
$messages [] = __("Please enter a valid Email address on row [" . $rowIndex . "]");
continue;
}
