Remove-AzConnectedMachineExtension -asjob not working as expected
Description
When running these commands everything works as expected.
Get-AzConnectedMachine -ResourceGroupName Arc | % { Get-AzConnectedMachineExtension -ResourceGroupName $_.ResourceGroupName -MachineName $_.Name | Remove-AzConnectedMachineExtension }
When trying to invoke the same, but adding the switch -asjob to the Remove-AzConnectedMachineExtension command
Get-AzConnectedMachine -ResourceGroupName Arc | % { Get-AzConnectedMachineExtension -ResourceGroupName $_.ResourceGroupName -MachineName $_.Name | Remove-AzConnectedMachineExtension -AsJob }
The correct number of jobs are started but all of them fail, giving me the message:
NullReferenceException: Object reference not set to an instance of an object.
Is this a bug or by design?
If by design, how do I work around it?

Can you upgrade to the latest release (0.6.0) and see if this issue is still there?
I couldn't reproduce this error. Remove-AzConnectedMachineExtension works fine for me for removing a CustomScriptExtension that I just created:
Remove-AzConnectedMachineExtension -MachineName testmachine -Name CustomScriptExtension -ResourceGroupName az-sdk-test -AsJob
In your error output, it seems like you are getting Null Reference Exception, and also some error related to Get-AzConfidentialLedger:
- For the null reference error, make sure you only call Remove-AzConnectedMachineExtension with the machine name and extension name, so you are not deleting an extension that doesn't exist - although the latest command will always ask you to input those two arguments
- For the error related to calling Get-AzConfidentialLedger that doesn't exist, make sure you don't call other commands while removing an extension, so that we can know which command is causing the error
Can you also share the result when running the latest module in debug mode?
@pejuborg - Please try with 0.8.0 of the Module and reactivate if you still see the issue: https://www.powershellgallery.com/packages/Az.ConnectedMachine/0.8.0
