According to https://icalendar.org/validator.html, the ics file is OK.

START:P looks suspicious. Could be "valid" as per the ICS spec, but definitely an odd period. PRODID says the file was produced by SabreDAV, is that correct?

tcitworld commented 8 months ago

Just found https://github.com/sabre-io/vobject/issues/467 so the issue should be fixed in the backend.

Front-end it might be easier to add a repair step to change durations of P in PT0S than to fix it in ICAL.js

Does the data comes from Exchange/Outlook in your case?

d-tamm commented 8 months ago

The data is a part of an export I made yesterday from another Nextcloud instance. Since this event is quite old, I cannot say how it has been generated from the beginning.
