Steps to reproduce:
- The issue has appered after updating from 6.0.30 to 6.0.34
- Errors in log - Something impossible has just happened and cannot convert value to string. I am not sure if these errors are related to one another.
Result:

I noticed the preprocessing failing is from official "Website certificate by Zabbix agent 2" template. There is "Discard unchanged with heartbeat": 6h and every 6 hours, the preprocessing works and i can see the data in history. So it looks like its working somewhat correctly, just the dependent items are missintepreting the 6 hour discard.
Expected:
No errors
