Trashbin Error - regularly

ℹ️ Support
1

My Setup is a Raspberry pi 4 4gbRam with Nextcloud 16.0.5.

Problem:
Everytime I want to enter the trashbin there is an error. (log below). I dont know if this maybe correlates to my backup system, wich is a rsync command in cron, to duplicate the data folder on to a second drive. The database and configuration gets backuped through the build in backup script (but the settings are withou data).

So everytime I run the commands (below) the trashbin works again fine. Everything else works fine as well, ncp-report is all ok and up.

sudo -i
cd /var/www/nextcloud
sudo -u www-data php occ trashbin:cleanup --all-users

Anyone else the same issue? What could be the problem?
