Powershell Hyper-V remote execution receives no response - powershell

Question

I have a work machine(A) and a different Hyper-V server (B) with virtual machines running.
If I connect to the Hyper-V server B with RDP and run Get-VM Where-Object {$_.State -eq 'Running'} I get a valid answer:
Name State CPUUsage(%) MemoryAssigned(M) Uptime Status
---- ----- ----------- ----------------- ------ ------
vm1 Running 2 2048 20:07:05 Operating normally
vm2 Running 0 1024 3.00:49:30 Operating normally
Next, I wrote a PS script to run on my work machine A:
$sess = New-PSSession $SETTING_SESSION_HOST
$commandStr = "Get-VM | Where-Object { `$_.State -eq 'Running' }"
#or a simple version: $commandStr = "Get-VM"
[console]::writeline("Executing: [{0}]", $commandStr)
$commandBlock = [scriptblock]::Create($commandStr)
$job = Invoke-Command -Session $sess -ScriptBlock $commandBlock -AsJob
Wait-Job $job
$vml = Receive-Job $job
foreach($m in $vml)
{
[console]::writeline("Executing: [{0}]", $m.Name)
}
$g = Format-List -InputObject $vml
[console]::writeline("format list: [{0}]", $g)
Here I would expect to see 2 lines containing "vm1" and "vm2" respectively. But I get an empty response:
Executing: [Get-VM | Where-Object { $_.State -eq 'Running' }]
format list: []
Any idea on how to get remote response from remote job?
Also, the execution time of the script is ~6 seconds (all spent in Wait-Job), while on the server it runs instantaneously.
EDIT: added -AsJob parameter
EDIT: fixed variables

Answer 1

may I suggest the following:
$sess = New-PSSession $SETTING_SESSION_HOST
$wml = Invoke-Command -Session $sess -ScriptBlock {Get-VM | where State -eq 'Running'}
$wml.Name
PS: while writing this i noticed you set $wml to Receive-Job $job but then you iterate through $vml so it might just be a typo v for w

Answer 2

After doing some debugging, I found the answer: when there's only 1 machine running, then the return result is an object of type Microsoft.HyperV.PowerShell.VirtualMachine, so this code works nicely:
$vml = Invoke-Command -Session $sess -ScriptBlock {Get-VM | where State -eq 'Running'}
$vml.Name
However, if there are more than 1 machine running, then the result is Object[], and the code I found out working is like this:
$vml = Invoke-Command -Session $sess -ScriptBlock {Get-VM | where State -eq 'Running'}
$len = $vml.length
if ($len)
{
[console]::writeline("Machine count: [{0}]", $len)
for ($i=0; $i -lt $len; $i++)
{
$m = $vml[$i]
[console]::writeline("machine: [{0}]", $m.Name)
}
}
else
{
[console]::writeline("Machine: [{0}]", $vml.Name)
}
Note that doing a foreach($m in $vml) doesn't seem to work for some reason.
The problem in my opinion is that the method is either returning an object or an array.
