Remote background job error with Using scope modifier

I receive the following error when attempting to run remote jobs on remote servers with $Using scope modifier. The local scope contains a scriptblock in a variable. Examples are shown in ‘help about_remote_jobs’ and ‘help wait-job -example’ with the same syntax I use. My example and error is below.

$server = Get-Content C:\script\serverlist.txt

$session = New-PSSession -ComputerName $server
$scriptblock = {Get-Process | Select-Object -First 5}
Invoke-Command -Session $session -ScriptBlock {Start-Job -ScriptBlock $Using:scriptblock} 

Error: The value of the using variable ‘$Using:scriptblock’ cannot be retrieved because it has not been set in the local session.

The syntax below works, but I would like the remote server to execute the scriptblock and start the background job.

 Invoke-Command -Session $session -ScriptBlock $scriptblock

you could use Invoke-Command with -AsJob parameter.

Invoke-Command -Session $session -ScriptBlock {param($sb) Start-Job -ScriptBlock $sb} -ArgumentList $scriptblock
