Get-AzDelegation returns an error when null

[anwather]

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Cmdlet          Get-AzDelegation                                   3.3.0      Az.Network

When I run the command as below an error is returned (the delegation does not exist) :-

Get-AzDelegation -Name nmeFunction -Subnet $subnet
Get-AzDelegation : Sequence contains no matching element
At line:1 char:1
+ Get-AzDelegation -Name nmeFunction -Subnet $subnet
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [Get-AzDelegation], InvalidOperationException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.Network.GetAzureDelegation

Would it be better if $null is returned instead when an object doesn't exist?

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @aznetsuppgithub.

@anwather , thanks for reporting. The return message is not good. Could you share debug message via setting $DebugPreference="Continue"?
