i used post object field but even this simple code that i put in function.php is not working
and posts are published

add_filter('acf/validate_value/name=persona', 'require_unique', 10, 4);
function require_unique($valid, $value, $field, $input) {
  if (!$valid) {
    return $valid;
  }

    $valid = 'This Value is not Unique';
  

  return $valid;
}
