Error on Ticket.php

Hello,

Recently we were unable to use projeqtor, from the log we got the following error:
2022-03-25 14:58:14.185 ***** ERROR ***** [V9.4.3] on file '/var/www/projeqtor/model/custom/Ticket.php' at line (54)
2022-03-25 14:58:14.185 ***** ERROR ***** [V9.4.3] cause = syntax error, unexpected ',', expecting ')'
2022-03-25 14:58:14.185 ***** ERROR ***** [V9.4.3]    => #2 /var/www/projeqtor/model/persistence/SqlElement.php (7971) -> class_exists()

We then tried to open Ticket.php and removed the extra comma. This seemed to do the job. We don't really know how that file could have been modified, as no users have direct access to the server.

Can you enlighten with this issue ?

Best regards,
