Dear support team,
Recently we upgraded our Zabbix version from 3.4 to 4.0 and our actions doesn't work due to this error :

We use Oracle DB 12.2.
[Z3005] query failed: [-1] ORA-00979: not a GROUP BY expression [select e.eventid,e.source,e.object,e.objectid,e.clock,e.value,e.acknowledged,e.ns,e.name,e.severity,max(es.suppress_until) from events e left join event_suppress es on e.eventid=es.eventid where e.eventid=213324 group by e.eventid order by e.eventid]

If the problem fixed in Zabbix 4.0.1, how can i download the source ?!

Best regards,
Alireza Zabihi
