JSON null is converted to "null"

XMLWordPrintable

    • S2401-2
    • 0.25

      Steps to reproduce:

      1. Create an item prototype that uses JSON path preprocessing to extract a field. This field can either be a JSON string or JSON null.
      2. Add a trigger prototype with the following expression: 
        length(last(/BackupPC/backuppc.host[{#HOST},error]))>0 
      1. Monitor the template via a Zabbix Proxy
      2. Since Zabbix Proxy 6.0.12 a JSON null is converted to the JSON string "null" causing the trigger to fire.

      Expected:

      • JSON null should not be converted to the string "null"
