I have a contact list with more than 600 entries that got migrated from owncloud to currently nextcloud 220.127.116.11. When I try to edit an exisiting contact, the webinterface says something like failed to save contact (translated from German).
The error I get in the servers log is this:
PRODID MUST NOT appear more than once in a VCARD component
This is what an exported contact that fails to save upon editing looks like:
BEGIN:VCARD VERSION:3.0 VERSION:3.0 VERSION:3.0 VERSION:3.0 VERSION:3.0 PRODID:-//ownCloud//NONSGML Contacts 0.4.0.1//EN PRODID:-//Sabre//Sabre VObject 3.4.2//EN FN:firstname N:;firstname;lastname;; X-QTPROJECT-FAVORITE:false\;0 REV:2017-06-05T09:50:17+00:00 EMAIL:email@example.com UID:deleted END:VCARD
The majority of my contacts look like this (multiple VERSION fields and two PRODID fields). So, has anyone seen this? Has anyone a suggestion on how to fix this?
Thanks in advance!
