The update to PHP 8.1 brings the following error.
Deprecated function: Return type of Ticketmatic\Model\Event::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in include() (line 51 of /var/www/html/vendor/ticketmatic/phpsdk/lib/Model/Event.php).
To reproduce this, simply update your local environment to PHP 8.1 and on the page where the library is called, the error appears.
