Hi all. Could anybody give me a clue, what should I do for the following issue.. Need to invoke asynchronous execution of Azure Runbook from parent runbook. Code in the parent runbook looks like this:

$DebugPreference = "Continue"
$AutomationAccountName = "aaaa"
$RunbookName = "test_child_rb"
$ResourceGroupName = "rgrgrg"

 $job = Start-AzAutomationRunbook -AutomationAccountName $AutomationAccountName -Name $RunbookName -ResourceGroupName $ResourceGroupName

The child runbook - is just
Write-Output "test_child" ,without any parameters.
Getting the error: "Object reference not set to an instance of an object."
The full output is following:

Sought all Az modules and got latest version 0.0.0
Cannot fetch PowerShell version due to exception: Object reference not set to an instance of an object.

test_DK_parent

Power-Shell runtime version: 5.1.
Tried to do for 7.2 as well, - got the similar error.
What might be the cause?
Thanks.
