@megheaiulian Can you post the original event. Once I have that I can fix the issue this week.

[megheaiulian]

Unfortunately I do not have the original event. This error shows up when syncing a cal.com (https://github.com/calcom/cal.com) event with the Nextcloud server via webdav.

[st3iny]

@SebastianKrupinski The error is right here:

server/apps/dav/lib/CalDAV/EventReader.php

Line 176 in 9836e9b

$this->baseEventDuration = $this->baseEvent->DURATION->getDateInterval();

The call to $this->baseEvent->DURATION->getDateInterval() returns an instance of DateInterval but $this->baseEventDuration is an int.

[SebastianKrupinski]

The call to $this->baseEvent->DURATION->getDateInterval() returns an instance of DateInterval but $this->baseEventDuration is an int.

@st3iny yes I saw that and made a fix for it, but wanted to see the original event to make sure there are no other issues. Thank you for the patch.
