Failed: cannot perform regular expression "\n\s?\n(.*)" match for value of type "string": pattern does not match

[toushin-taishi]

Hello, I am getting the following error: "1. Failed: cannot perform regular expression "\n\s?\n(.*)" match for value of type "string": pattern does not match" for the item Jitsi Videobridge Stats when installing the template on Zabbix 5.0.5. I am using zabbix agent version 3.0.12 on the server running the jitsi service.

curl -s http://localhost:8080/colibri/stats is working as intended.

Could you please tell me how to resolve the issue?

Thanks in advance!

Wel...It's known issue that Zabbix have very problematic compability in regex versions... Espesially, that i wrote this template in 4.2 version. Since 4.4 Zabbix are written in Go(previous C language). Please, Let's try a old version (with User Parameters) , should work on your version.

Hi, thanks for the reply. Unfortunately, version 1.0 also does not work with Zabbix version 5. I am getting the following errors on all items:
