Event download as ICS file

[Former Community Member]

I've created a event using foundation event component (/libs/collab/calendar/components/event) and set the required values. But if I try to download the event ICS file then it's throwing following exception:

com.day.cq.wcm.core.impl.WCMDebugFilter Exception: null java.lang.NullPointerException

It appears from the stacktrace that event timezone is set to null. I don't see how to set it or am missing anything else.

Thanks,

Issue has been filled (CQ5-34388) internally.  As a workaround manually set the timezone. Ex:- for geometrixx "/content/geometrixx/en/events/shapecon/jcr:content/par/event/event" path create a property called "timeZone" of type "String" and assign value as "Asia/India" which is IST time zone.
