Rajeev Pentyala – Microsoft Power Platform

I got the following exception while executing a PowerShell script in my Azure DevOps pipeline step.

Import-Module : Could not load type 'System.Management.Automation.PSSnapIn' from assembly 'System.Management.Automation, Version=7.2.5.500,

Reason:

• I used following ‘pwsh‘ task in my YAML file to execute the PowerShell script.

steps:
- pwsh: |
    <My Script>
  env:
    SYSTEM_ACCESSTOKEN: $(System.AccessToken)
  displayName: 'My Task'
  condition: succeeded()

• For unversed, pwsh is the cross-platform edition of PowerShell built on .NET Core / .NET 5+; by contrast, powershell is the executable name of the legacy Windows PowerShell edition (v5.1-), built on the Windows-only .NET Framework (v4.8-).
• The issue is ”System.Management.Automation’ is built on .Net Framework and ‘pwsh‘ can’t be used in this case.

Fix:

• Replace pwsh task with powershell task in YAML file.

steps:
- powershell: |
    <My Script>
  env:
    SYSTEM_ACCESSTOKEN: $(System.AccessToken)
  displayName: 'My Task'
  condition: succeeded()
