Get-AzADAppCredential > MSGraph.Autorest: Object reference not set to an instance of an object

[erwinkramer]

Description

I've hit Object reference not set to an instance of an object. on a script. But I have a hard time reproducing it. All runs are doing fine today.

I'm using module Az version 8.1.0 as you can see in the trace.

Issue script & Debug output

@VeryEarly , do you have any insight to this error message?

[VeryEarly]

Hi @erwinkramer this looks related with PowerShell "ForEach-Object -Parallel", we cannot identify the root cause from Get-AzADAppCredential if no further detail provided.

[dingmeng-xue]

If the issue comes from line of Get-AzAdAppcredtial | Where-Object, I believe other Get-{} cmdlet with the same pattern should have similar issue.

@erwinkramer , let's keep this issue open for a while. If you hit the issue again, please share to us.
