Custom variables in TFS Release Management

Question

I'm using TFS 2017.1 Builds and Release feature. In my release definition, I have a couple of release variables which I need to refer in my PowerShell task (execute on remote machine). So far, I've tried the following options but couldn't get it to work.

Added an Execute PowerShell task to store release variables into Environment variables:

$releaseVaraiables = Get-ChildItem Env: | Where-Object { $_.Name -like "ACL_*" } 
Write-Host "##vso[task.setvariable variable=aclVariables]$releaseVaraiables"

Added an Execute PowerShell on remote machine task:

Here I can't read the Environment variables (maybe because this is remote machine task?)

Write-Verbose "problem reading $env:aclVariables" -Verbose

Then I tried passing the environment variable as an argument, but that didn't work either

param
(
    $RbacAccessTokenParams
)

$RbacAccessTokenParams.GetEnumerator() | % {$_.Name}
$RbacAccessTokenParams | % {
    Write-Verbose "variable is $_" -Verbose
    Write-Verbose "name is $_.Name" -Verbose
    Write-Verbose "value is $_.Value" -Verbose
}

This is how I passed as argument

-RbacAccessTokenParams $(aclVariables)

What I'm missing here?

I've tested your scenario on my side with TFS 2017.3.1, and it works when pass the environment variable as an argument. You can upgrade your TFS first and try again. Attach my steps for your reference:
