Perl regex syntax no longer accepted in any filter (plugin 4.2)

Describe the bug After update to 4.2.1 plugin (and grafana 8.1.1) any panel with an item/application/host/group filter that uses Perl regex syntax will show no-data. Using simpler regex syntax shows data as normal. Tried to switch from old “Graph” viz to the new “Time series” without any change in behaviour.

Expected behavior Time-series graph shown also for Perl regex syntax filters as the same syntax worked previously (grafana 7.x/8.0 and plugin 4.1.5). Edit: it also works with grafana 8.1.2+plugin 4.1.5 (but that has other issues)

Since this issue is quite critical and it’s a blocker for many users, I decided to release it as soon as possible. So here’s a 4.2.10 release https://github.com/alexanderzobnin/grafana-zabbix/releases/tag/v4.2.10 Plugin also submitted to grafana.com, but it may take time to verify. So if you want to upgrade, you can run

grafana-cli --pluginUrl https://github.com/alexanderzobnin/grafana-zabbix/releases/download/v4.2.10/alexanderzobnin-zabbix-app-4.2.10.zip plugins install alexanderzobnin-zabbix-app

then restart grafana server

Any update in this? It is really critical. Regular expressions are widely beeing used in Grafana. So if you broke regexp, you broke many things!
