$CheckCommand variable not defined in framework_cache.psm1

[dr-roshyara]

I am trying to connect my icinga2 to monitor windows host using powershell framework. the connection is all ok . However I still have problem . So let me describe the issue:

Issue:
The Icinga for Windows service check daemon reported a pending status for the icinga_powershell_memory service. CPU Check is also pending. If I apply the commands locally, its all working. api connection is established. However the rest api does is not getting any informatoin.

The daemon encountered an exception during the execution of a PowerShell plugin,
with an error related to the recognition of the term "". Troubleshooting Steps and Findings:

1. Endpoint Health Check:
   Ensured that 'windows host machine' is responsive and healthy.
   Checked for any issues on the Windows host that might affect communication with Icinga.

2. Event Viewer Check:
   Explored 'System' and 'Application' logs on 'windows host machine' in the Event Viewer.
   Checked for any WinRM-related errors or warnings.

3. Icinga API Connection:

Investigated API connection warnings and disconnections for the 'icinga' identity.
Configuration Update:
Observed the receipt and application of configuration updates from 'icinga'.

2. API Client Connection:
   Monitored API client connections and disconnections for 'icinga'.

• WinRM Port and Firewall:
  Identified and resolved an issue with WinRM port (5665) connectivity by adding a firewall rule.
  Confirmed successful connectivity using Test-NetConnection.

• Icinga PowerShell Script Execution:
  Encountered a specific error related to the recognition of "" during the execution of a PowerShell script.

• Check PowerShell Script/Command:

Investigated the $CheckCommand variable, which is expected to contain a valid PowerShell command or script path.
However I could not find the solution .

• Event Log error in windows host machine
  In windows Event log file the error is as follwoing
