NC = 19.0.6
Preview Generator = 2.3.0
PHP = 7.3.21
My Preview Generator Pre-run
./occ preview:generate-all -vvv
terminated after 12 hrs. succesfully.
I’m adviced to add this to my system cron:
php /var/www/nextcloud/occ preview:pre-generate.
To test the validity / outcome of the above, I issue:
sudo -u www-data php /var/www/nextcloud/occ preview:pre-generate
in my terminal, and receive this error list:
An unhandled exception has been thrown:
