Every time the cron runs it logs this error:
[Magento\Framework\Exception\LocalizedException] Invalid Document Element 'group': Missing child element(s). Expected is ( job ). Line: 24 cron:run [--group="..."] [--bootstrap="..."]
the crontab -e shows this at line 24:
* * * * * /usr/bin/php7.0 /var/www/html/store/bin/magento cron:run 2>&1 | grep -v "Ran jobs by schedule" >> /var/www/html/store/var/log/magento.cron.log
I checked official documentation and didn't found any significal differences between these lines aside from paths. Does anyone knows what "group" is missing and how do i fix that??
