Hello, we have updated wordpress and anspress plugin, after that our custom code who adds and safes custom fields not working. Do not saves fields. Can you please check whats wrong?

Code:

/**
 * Adds a PDF field to AnsPress question form.
 *
 * @param array $form Form arguments.
 * @return void
 */
function my_custom_question_field( $form ) {
	
 // field.
  $form['fields']['date'] = array(
    'label'   => __( 'Jūs? ar ?mogaus, d?l kurio klausiate gimimo data ir laikas:' ),
    'desc'    => __( 'Tiksli data svarbi sudarant atsakym?.' ),
    'subtype' => 'text', // Default type is set to input.
    'attr'    => array(
      'placeholder' => 'Pvz.: 1991-08-25 14h 20min',
    ),
  'sanitize'      => 'text_field', // This sanitize will be applied by default for url field.
  'validate'      => 'required,max_string_length', // Require and check length of string.
  );
	
	 $form['fields']['city'] = array(
    'label'   => __( 'Gimimo miestas' ),
    'desc'    => __( '' ),
    'subtype' => 'text', // Default type is set to input.
    'attr'    => array(
      'placeholder' => 'Pvz.: Vilnius',
    ),
  'sanitize'      => 'text_field', // This sanitize will be applied by default for url field.
  'validate'      => 'required,max_string_length', // Require and check length of string.
  );	
	
  return $form;
}
add_filter( 'ap_question_form_fields', 'my_custom_question_field' );

/**
 * Save a upload field.
 */
function my_save_pdf_uploads($post_id,$post) {
 $form = anspress()->get_form( 'form_question' );
	// Get all sanitized values.
	$values = $form->get_values();
  if ( ! add_post_meta( $post_id, 'user_date', $values['date']['value'], true ) ) {
update_post_meta( $post_id, 'user_date', $values['date']['value'] );
}
 if ( ! add_post_meta( $post_id, 'user_city', $values['city']['value'], true ) ) {
update_post_meta( $post_id, 'user_city', $values['city']['value'] );
}
  
}
add_action( 'ap_processed_new_question', 'my_save_pdf_uploads' );
