Invoke-IcingaCheckScheduledTask works directly but fails via Exit-IcingaExecutePlugin when using -TaskPath array

[dv-27]

Hi team,

I found a reproducible issue with Invoke-IcingaCheckScheduledTask when called through Exit-IcingaExecutePlugin.

Environment

icinga-powershell-framework: 1.14.2
icinga-powershell-plugins: 1.14.1
Windows Server (PowerShell 5.1)
Icinga 2 command path uses the standard wrapper (PowerShell Base + Exit-IcingaExecutePlugin)
What works (direct invocation)

PS C:\Windows\system32> & 'C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe' -NoProfile -NoLogo -ExecutionPolicy Bypass -Command "Invoke-IcingaCheckScheduledTask -TaskPath @('\Icinga*') -Verbosity 3"

0

Expected tasks are returned (e.g. \Icinga\Icinga for Windows...)
Exit code: 0

What fails (wrapper invocation)

PS C:\Windows\system32> & 'C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe'   -NoProfile -NoLogo -ExecutionPolicy Bypass   -Command "try { Use-Icinga -Minimal } catch { Write-Output 'Framework not loaded'; Write-Output $($_.Exception.Message); exit 3 }; Exit-IcingaExecutePlugin -Command 'invoke-icingacheckscheduledtask' -TaskPath @('\Icinga*') -Verbosity 3"

[INFO] Scheduled Tasks: No checks added to this package (All must be [OK])
|

Exit code: 3

Expected behavior
Wrapper invocation via Exit-IcingaExecutePlugin should behave identically to direct invocation and return the same filtered scheduled tasks for -TaskPath @('\Icinga*').

Actual behavior
Only the wrapper path fails (empty package / no checks added), while direct invocation works with the same arguments.

Notes

This is reproducible consistently on the same host/session.
The issue appears specific to the wrapper argument handling path, not the plugin function itself.
Thanks for taking a look.
