    Description

      Steps to reproduce:

      1. Apply the attached template to a host, it contains a dependent item with heartbeat preprocessing
      2. Send valid data
      zabbix_sender -z zabbix_server -s zabbix_host -k heartbeat -o "123" 

      data gets recieved and processed properly

      1. Send invalid data
      zabbix_sender -z zabbix_server -s zabbix_host -k heartbeat -o "abc" 

      heartbeat_dep becomes unsupported

      1. Send valid data
      zabbix_sender -z zabbix_server -s zabbix_host -k heartbeat -o "123" 

      heartbeat_dep is still unsupported <- BUG

      Result:

      heartbeat_dep is still unsupported even with valid data
      Expected:
      heartbeat_dep becomes supported after sending valid data

      Notes:
      **

      • Sending different valid data recovers the item -> heartbeat is causing the issue
      zabbix_sender -z zabbix_server -s zabbix_host -k heartbeat -o "456" 

      • Only dependent items seem to be affected, I wasn't able to reproduce the issue using other item types
