I got the following error from my nextcloud cron job recently:


Sabre\DAV\Exception\BadRequest: VCard object with uid already exists in this addressbook collection. in /var/www/nextcloud/apps/dav/lib/CardDAV/CardDavBackend.php:667

#11 {main}

It seemed to happen three times and then stop. Is it anything to be concerned about?

We have the same problem here.

In the Admin / Overview page, I get “Last background job execution ran 1 hour ago. Something seems wrong.”
In the Admin / Basic settings page, I get “Last job execution ran 1 hour ago. Something seems wrong.”
We use “Cron” for Background jobs option.

When running cron.php manually (using “sudo -u apache /usr/bin/php -f /var/www/nextcloud/cron.php”), I get following error:

But we even don’t use CardDAV and CalDAV - and the “Contacts” App is disabled.

We are currently running on 22.2.0.

I have created a github issue for Nextcloud here. I mentioned your issue, but perhaps you would like to add you experience to the issue as multiple reports might be taken more seriously.
