pwsh - output not returned to puppet if Automatic Transcription is enabled

[scosens]

Describe the Bug

on windows nodes, when Automatic transcription is switched on for Powershell Core (HKLM\SOFTWARE\Policies\Microsoft\PowerShellCore\Transcription\EnableTranscripting), puppet no longer gets the output from an exec using the pwsh provider

Expected Behavior

when puppet executes an Exec resource using the pwsh provider and with logoutput => true, any output produced by the powershell commands should be returned to puppet and displayed either in the console or in event viewer.

Steps to Reproduce

Steps to reproduce the behavior:
on a windows node:

1. ensure registry key HKLM\SOFTWARE\Policies\Microsoft\PowerShellCore\Transcription\EnableTranscripting either does not exist or = 0
2. extract attached example module .zip to C:\ProgramData\PuppetLabs\code\environments\production\modules
3. in a terminal window, run:

   puppet apply -e "include example" --test

4. console output will contain the message 'this uses the pwsh provider', along with 'executed successfully'
5. set registry key HKLM\SOFTWARE\Policies\Microsoft\PowerShellCore\Transcription\EnableTranscripting = 1
6. repeat terminal command:

   puppet apply -e "include example" --test

7. console output will no longer contain the message 'this uses the pwsh provider'. 'executed successfully' still appears.

Environment

replicated against:

• puppet agent version 5.5.16,
• powershell module 3.0.1 & 6.0.0
• windows server 2019

Additional Context

example.zip

Using exec provider 'powershell' successfully returns the script output, even with automatic transcription enabled. Automatic transcription for standard Windows Powershell is enabled through a Group Policy item, however Powershell Core does not obey this setting, instead requiring it to be enabled in the registry as above.
