Error: content provider returned null on insert #1851
Description
Problem scope
- I'm sure that this is a DAVx⁵ problem.
App version
- I'm using the latest available DAVx⁵ version.
Android version and device/firmware type
Android 14 and 16
Steps to reproduce
I exported a calendar event from my old phone and imported it into an agenda in Nextcloud.
In DAVx5 I enabled syncing for the agenda.
Now DAVx gives an error 'content provider returned null on insert' every time it syncs.
Without this calendar event, the error does not show.
Is it DAVx that generates the error? Or Android? Is it because of the DTEND that is set to 1970? Is there anything DAVx can do to prevent the error and thus not show the notification all the time?
