Function $posted_data not working after 5.2

Can you tell us if the next update will fix the problem or if another function exists?
Thank you so much !

 // Create the new wordpress action hook before sending the email from CF7
add_action( 'wpcf7_before_send_mail', 'my_conversion' );
   function my_conversion( $contact_form ) {
   $submission = WPCF7_Submission::get_instance();
  $form_id = $contact_form->id();
  // Get the post data and other post meta values
if ( $form_id == 1363 ) {
if ( $submission ) {
    $posted_data = $submission->get_posted_data();
    $remote_ip = $submission->get_meta( 'remote_ip' );
    $url = $submission->get_meta( 'url' );
    $timestamp = gmdate("Y-m-d H:i:s", $submission->get_meta( 'timestamp' ));
    $title = wpcf7_special_mail_tag( '', '_post_title', '' );
