wmi | Package wmi provides a WQL interface to Windows WMI

For reference, this error can be reproduced on both PowerShell versions 5.1 and Core. The steps to reproduce is passing a System.Management.Automation.PSObject as argument to the .ShouldProcess(String) overload. It makes sense, by looking at your comment mentioning a serialized object. In below example, if the System.Diagnostics.Process object is not serialized it works properly on both versions.

Since you're doing

I don't understand from your question what command you are actually trying to run, nor do I have or use Windows, however I get the sense that your command is exiting with an error that is upsetting you.

If commandX fails on macOS or Linux, the normal thing to do is run a second command after it that will succeed and so the caller will not get upset. So maybe you can try that technique:

You can give pygrabber a shot. "# This code lists the cameras connected to your PC:" (source)

There are several WMI classes to access Disks and Partitions information:

• Win32_Volume
• Win32_DiskDrive
• Win32_DiskPartition

And these two, which relate the previous ones to each other:

• Win32_DiskDrivePhysicalMedia
• Win32_DiskDriveToDiskPartition

Specifically using Win32_Volume you can access the GUID of the existing partitions. You can test it from shell:

Can I somehow self-elevate it by just having the admin credentials?

No you cannot. UAC is designed to prevent exactly what you are trying to do. Related Q&A:

• elevate without prompt - verb runas start-process
• UAC Getting in the Way of EXE Install Powershell
• Powershell provide credentials for RunAs

There may be many workarounds, but they all will have in common that you have to go to your machines (locally or remotely) at least once, gain administrative privileges and prepare something, e. g.:

• A scheduled task that runs under your local administrator account or under SYSTEM and triggers the execution of your script
• Disabling UAC (temporarily) (not recommended either way)
• Installing any remote management software, services or accounts (with extra run as background job privilege)

While the python:3.8.0 image has a windows architecture available, it looks like it's pulling the linux version from that tag. You can test this by adding the command uname -srm to the first line of your test scripts.

I wasn't able to get a windows docker image for python running on a shared runner, but I was able to install python 3.8 on a runner with the following minimal .gitlab-ci.yml:

What you're experiencing is merely a display problem:

• Both your Select-Object calls produce output objects with 4 or fewer properties whose types do not have explicit formatting data associated with them (as reported by Get-FormatData).

• This causes PowerShell's for-display output formatting system to implicitly render them via the Format-Table cmdlet.

• The display columns that Format-Table uses are locked in based on the properties of the very first object that Format-Table receives.

• Therefore, your second Select-Object call, whose output objects share no properties with the objects output by the first one, effectively produces no visible output - however, the objects are sent to the success output stream and are available for programmatic processing.

A simple demonstration:

Here's a streamlined version of your code, which heeds the comments on the question:
