Couldn’t parse iCalendar resource

---

My university (MUNI) provides an iCal for my personal calendar on its Information System. It would be incredibly handy to have it available on my phone, but for some reason I always get the aforementioned error. NextCloud parses it without problems however. Is there a way I could help debug this? (Though I’m not keen on sharing my personal iCal publicly, for obvious reasons, but I don’t really mind sharing it privately.) Cheers!

@jurf Hello,

Please send the URL of the calendar per direct message (chat) or to play@bitfire.at. We can can only have a look at it when we can reproduce the problem.

Sent, thanks.

Thanks for the URL. It’s the same problem as https://forums.bitfire.at/topic/1849/couldn-t-parse-icalendar-source-on-validated-ical-source: The iCalendar contains DTSTAMP;TZID=Europe/Prague:20190104T155229, which is invalid (because DTSTAMP must be given as UTC) and can’t be parsed by ical4j.

Please tell your IT that the iCalendar is invalid and that it should be fixed on server side.

Thanks; contacted IT support.

BTW, could you at least make the error a bit more helpful? The current one is really vague.

OK, got a reply, the feed is now fixed, thanks a lot for the help!

It still happens a lot with standard Google calendars. Sometimes it syncs sometimes not, sometimes only one but most times all 5 of them. Is there any way to get a log file?
