Azure DevOps: Powershell 'Get-AzSubscription' is not recognized

Question

I am deploying an ARM template from azure DevOps using Azure PowerShell as shown below.

This is subscription level deployment. I am getting below error.

The term 'Get-AzSubscription' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Install-Module -Name Az -AllowClobber -Scope CurrentUser
Import-Module Az
$context = Get-AzSubscription -SubscriptionId xxxxxxxx
Set-AzContext $context


New-azdeployment -Name "SKL" -Location westeurope -TemplateFile .\delegatedResourceManagement.json -TemplateParameterFile .\delegatedResourceManagement.parameters.json

Answer 1

You need to specify the task version: 4.* (Preview) or higher to use the Az powershell module:
