User verification does not work in contact form 7 in version 4.1.1

Question

I need to create a form with a custom validation field in contact form 7. It does not work with the latest version (4.1.1) of contact form 7, but it works in an older version.

I created a field to get the coupon code from the form. I want to confirm this entry if the coupon starts with "HIP". My code is below:

add_filter( 'wpcf7_validate_text', 'your_validation_filter_func', 999, 2 );
add_filter( 'wpcf7_validate_text*', 'your_validation_filter_func', 999, 2 );


function your_validation_filter_func( $result, $tag ) {
$type = $tag['type'];
$name = $tag['name'];      
if ( 'coupon_code' == $name ) {
$the_value = $_POST[$name];

        $myresult = substr($the_value, 0, 3);
        if($myresult=="HIP")
        {
            $result['valid'] = true;
        }
        else
        {
            $result['valid'] = false;
            $result['reason'][$name] = "Not a valid coupon code";
        }
}

return $result;
}

Give me a suggestion, please.
