Problem in trigger creaton of custom script

[raunjuu]

Hello,

I am trying to use some guys made custom script for .jks certificate file certificate monitoring:

https://github.com/villisco/zabbix-keystore-discovery

However when I want to import the triggers the expressions do not work. I tried to do it to template.xml it also does not work. It does not like to seem to want this part:
JVM keystore:jvm.keystore.enddate[{#KEYALIAS}].last()} - {JVM keystore:jvm.keystore.enddate[{#KEYALIAS}].now()
Somehting has changed between zabbix versions over time so now it wont accept this expression?

Any workaround on how I can construct this expression without reworking the script?

The thing was written for Zabbix v, 5.2 or earlier. The syntax of triggers was changed in version 5.4
You'd need to go to documentation about Zabbix 5.0 - link - check what trigger supposed to do based on function they use in that github solution, then go to functions of modern version - link - find corresponding function - rewrite the expression for modern syntax
