Initial Setup

Recently I implemented a UserParameter via PowerShell script to monitor Veeam Backup and Replication Job information, as a means to universally have this information in Zabbix (current Veeam API limitations meant that clients running Hyper-V could not be queried to the same extent as ESXI).

The UserParemeter is defined in ./zabbix_conf.d/VBR-userparameters.conf:

`UserParameter=veeam.jobs.powershell,powershell -ExecutionPolicy Bypass -File "C:\Scripts\VBR-GetJobInformation.ps1" $1`

On machines running Zabbix Agent2 versions up to 7.0.11 this works fine and returns the correct information.

Steps to reproduce:

1. Update Agent2 to version 7.0.12
2. Attempt to execute existing Userparameters that rely on PowerShell script (as described above)
3. Error appears in logs, and checks time out in Zabbix Console

Result:
