Azure DSC Configuration Issue - azure

Question

Basically I am just trying a very basic thing of accessing the VM details using Azure DSC.
I have done the following
Added a new Credential(which holds the username and password) and Variable(which holds the subscriptionId) under Shared Resources of my
automation account
Have implemented the following DSC code for retrieving the VM details: I am able to complie this file in the portal it generates
the .MOF file as well. But when I try to apply this to a node in the
portal I get the following error:
PowerShell DSC resource
MSFT_ScriptResource failed to execute Set-TargetResource
functionality with error message: The term
'Get-AutomationPSCredential' 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
Please note that the code written inside the SetScript executes successfully in a runbook!!!!!!

Command Get-AutomationPSCredential works in Azure Automation.
For DSC, pass credentials using Get-Credential.
Add parameter
[Parameter()]
[pscredential]
$Credential
And replace Get-AutomationPSCredential with Get-Credential -Credential $Credential.
