@ganglia said in Calendar sync error with already removed item:
I have had a calendar item that I removed some time ago from the server-side, but for some reason that removed item never got removed from my Android.
The event is a recurring event starting on 24.8.2016 14:00 GMT:
DTSTART;TZID=Etc/GMT:20160824T140000, which is repeated weekly (
So, instances are at 14:00 GMT, too, but the excluded instances of your event are all at 15:00 GMT:
This would explain why those exclusions are not shown on your Android device. If you take a set of all 14:00 GMT instances and remove the 15:00 values, the set stays the same, i.e. actually no instances are excluded.
SO I manually removed the item from my Android. On the very next sync attempt of DAVdroid, I got an error. Ever since then each sync attempt results in this error, and no calendar events get sync’d anymore.
For an unknown reason, your server returns 500 Internal server error. Please contact your server vendor/support about this, because it does not seem to be a DAVdroid problem.
What can I do to resolve this error and get back to sync’ing my calendar on my Android?
A quick solution should be to delete the whole recurring event (not only an instance) on your Android device, which should
DELETE it from your server, too.
Which server software do you use?
