NC20: Can't synchronize contact "This parser only supports VCARD and VCALENDAR files"

shiftag · February 9, 2021, 3:00pm

Nextcloud version (eg, 20.0.5): 20.0.7
Operating system and version (eg, Ubuntu 20.04): slackware-current_x86_64
Apache or nginx version (eg, Apache 2.4.25): 1.12.2
PHP version (eg, 7.4): 7.4.13

The issue you are facing:

I can’t synchronize the contacts. I got an HTTP error 500 from nextcloud server. It seems, the issue is related to a the parser for VCARD/VCALENDAR.

Davx application dump the following error:

SYNCHRONIZATION INFO

I have set up an appointement in NC-calendar itself with attendee.
When i try to connect “https.///z-app-generated–contactsinteraction–recent/” i get “This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client.”
Don’t know if it’s related.

In the “DAVx5”-log i find “URL: https:///z-app-generated–contactsinteraction–recent/
Read-only: 1”

Something wrong? How to get rid of the error?

besimux · March 12, 2021, 2:45pm

I recognized “contact lists” of my android addressbook beeing set to “All” somehow. Switched back to “DAVx5”. Don’t know yet if this solves the problem.

besimux · March 12, 2021, 3:07pm

DAVx5-error seemingly disapppeared. But “This parser only supports VCARD and VCALENDAR files” remains". So no relation.

janci · March 23, 2021, 5:41pm

I see same error message in logging of nextcloud.

I did stop all davx5 clients and switch off online account in my gnome linux desktops.

When opening contacts app in webgui in nextcloud error message imediatelly popUP in log.

I find out that its happend only if user has not “recently contacts”.
User who has “recently contacts” can open contacts app without error message in log.

here is my thread about this problem

chrissi55 · May 27, 2021, 9:35am

Same here with NC 21.0.2 under ubuntu 20.04.2 with PHP 7.4

Error messages

Sabre\VObject\ParseException: This parser only supports VCARD and VCALENDAR files

But i can not figure out which client causes the problem. It is definitely no fresh install.
All my users have contacts, so don’t know where to look at …

Thanks for help.

Bernd_Wechner · September 13, 2021, 12:11pm

Likewise and I would like to know why my log file is flooded with these fatal errors. It bugs me how cryptic Nextcloud error messages can be to honest. You think this message would include information regarding which client caused it and what it was attempting to parse.
