Many "Undefined array key" warnings

[michael-markevich]

I use the current snapshot of the plugin, RC 1.6.5 and PHP 8.2.7. I have received a lot of annoying warnings:

PHP Warning:  Undefined array key "port" in /var/www/roundcubemail-1.6.5/plugins/calendar/drivers/caldav/caldav_client.php on line 54

Hey @michael-markevich
Any workaround or fix you found?

I am unable to create event with participants (without participants working), getting error:
