Availability report: items with UNKNOW, and message 'Undefined offset: 0'.

[cesarsj]

This week we tested the innobackupex for online backup. We were apprehensive, confident that nothing would affect the system. Zabbix has also been upgraded from version 4.0.2 to 4.0.3. But then the following message appeared in the Availability report:

Undefined offset: 0 [zabbix.php:21 → require_once() → ZBase->run() → ZBase->processRequest() → CController->run() → CControllerProblemView->doAction() in app/controllers/CControllerProblemView.php:257]

What could have caused this? Are there multiple items with UNKNOW appearing. But only when the filter is set to 'all'. By selecting host group per host group one by one, these items do not appear.

there is a bug that hits non super admins if show suppressed is checked, should be fixed in 4.0.4

Sorry, could you explain better? I did not understand the cause. Is there no way to fix it right now? Just updating to version 4.0.4?

I think it's this one https://support.zabbix.com/browse/ZBX-15373

Hello. The error has disappeared. Fixed the HOST.NAME macro and updated to version 4.0.4. Apparently, the bug has been fixed.
