@blackdam said in HTTP 500 error when syncing with Nextcloud:
It looks like it’s trying to sync an entry that isn’t on my calendar anymore. When I search Etar for the entry name given in the debug info, it shows no results.
Yes, there’s a recurring event in the database which doesn’t have a valid occurrence because every single occurrence is deleted. In this case, the event shouldn’t be in the database at all.
You can either delete the event manually (with adb) or deselect the calendar in DAVx5, force sync, then select it again and sync again. Then all local changes since the last sync are lost and the “ghost event” won’t be uploaded again.
