Bugreport: iCal-Import error

Joomla! 5.1.3

Jevents 3.6.82

PHP Version 8.3.x (same problem with 8.1.x or 8.2x2)


Problem comes, when I try to import iCal

Server Error Message:
Got error 'PHP message: PHP Warning: Undefined array key 47 in /...../components/com_jevents/libraries/iCalImport.php on line 477

and there is an E-Mail with
Subject: ICal import failed
Message: Ical 'GV' failed to import correctly


Line 477 in iCalImport.php is

if (!array_key_exists("EXDATE", $this->cal[$parent][$this->eventCount])) {.... }

Has anyone an idea or bugfix?

Thanks
Carsten
