PSResourceList set operation fails when warning contaminates stdout JSON #1999
Description
Prerequisites
- Write a descriptive title.
- Make sure you are able to repro it on the latest released version
- Search the existing issues.
Steps to reproduce
On a fresh Windows Server 2025 box, the Microsoft.PowerShell.PSResourceGet/PSResourceList DSC resource fails during a set operation. This is because by default the modules path isn't added to the PATH throwing a warning like:
The installation path for the script does not currently appear in the CurrentUser path environment variable. To make the script discoverable, add the script installation path, C:\Users\vmadmin\Documents\PowerShell\Modules, to the environment PATH variable.
Because PSResourceGet runs cmdlets in the same runspace as the script, the warning reaches the stdout pipe that DSC reads as JSON, causing the verification step to fail.
To reproduce the issue, create a fresh Windows Server 2025 box (I used Azure) and run:
$in = @'
$schema: https://aka.ms/dsc/schemas/v3/bundled/config/document.json
resources:
- name: Install required modules
type: Microsoft.PowerShell.PSResourceGet/PSResourceList
properties:
repositoryName: PSGallery
trustedRepository: true
resources:
- name: Pester
version: 5.7.1
- name: PSScriptAnalyzer
version: 1.25.0
'@
dsc config set --input $in Expected behavior
Return result through `dsc.exe`.Actual behavior
