Unable to execute Get-GceManagedInstanceGroup for specific instance group

[marcelvanwaaijen]

I am trying to run Get-GceManagedInstanceGroup for a specific managed instance group on a Windows managed instance in GCP.

When I run just the command, it executes fine, but outputs all managed instance groups:

Get-GceManagedInstanceGroup

BaseInstanceName  : xxxx
CreationTimeStamp : 2024-06-01T00:00:00.000-00:00
CurrentActions    : Google.Apis.Compute.v1.Data.InstanceGroupManagerActionsSummary
Description       :
....

But when I specify the name of a specific managed instance group, I get an error specifying that the -Zone must be specified:

Get-GceManagedInstanceGroup -Name "my-mig"

Get-GceManagedInstanceGroup : Parameter Zone was not set and does not have a default value.
At line:1 char:1
+ Get-GceManagedInstanceGroup -Name my-mig
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (:) [Get-GceManagedInstanceGroup], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Google.PowerShell.Compute.GetManagedInstanceGroupCmdlet

And when I add the -Zone, I get an error saying that I also must specify -Region:

Get-GceManagedInstanceGroup -Name "my-mig" -Zone "us-west1-a"

Get-GceManagedInstanceGroup : Parameter Region was not set and does not have a default value.
At line:1 char:1
+ Get-GceManagedInstanceGroup -Name "my-mig" -Zone "us-west1-a"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (:) [Get-GceManagedInstanceGroup], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Google.PowerShell.Compute.GetManagedInstanceGroupCmdlet

Then, when I specify both -Zone and -Region, I get an error saying that I can't use -Zone and -Region together with -Name:

Get-GceManagedInstanceGroup -Name "my-mig" -Zone "us-west1-a" -Region "us-west1"

Get-GceManagedInstanceGroup : Parameters -Region and -Zone cannot be used together with -Name.
At line:1 char:1
+ Get-GceManagedInstanceGroup -Name "my-mig" -Zone "us-west1-a" -Region ...

+ CategoryInfo          : InvalidOperation: (:) [Get-GceManagedInstanceGroup], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Google.PowerShell.Compute.GetManagedInstanceGroupCmdlet

And when I leave out the -Name and only specify -Zone and -Region, I am prompted to specify the Name:

> Get-GceManagedInstanceGroup -Zone "us-west1-a" -Region "us-west1"
Supply values for the following parameters:
Name: 

On my own laptop I am able to run the command Get-GceManagedInstanceGroup -Name "my-mig" -Zone "us-west1-a" successfully for zonal MIGs.
