Adding VM tags workflow

Hi,

Based on  this blog - https://code.vmware.com/forums/3055/vrealize-orchestrator#579949, I am testing the workflow to add tag to VMs by invoking a powercli script from vRO workflow.  In short here is what mentioned in the blog.

$DC = "%%location%%"
$appCode = "%%appcode%%"

If ($DC -eq "DCNAME1") { $vc = "VCNAME1" }
If ($DC -eq "DCNAME2") { $vc = "VCNAME2" }

##### Imports Core Module  #####
If (!(Get-Module VMWare.VimAutomation.Core)) { Import-Module VMWare.VimAutomation.Core }

##### Connects to vCenter  #####
Connect-VIServer $vc -Credential $creds | Out-Null

##### Validates tag exist, and if not, creates it, and attaches it to specific category  #####
If (!(Get-Tag $appCode -ErrorAction SilentlyContinue))
{
    New-Tag -Name $appCode -Category (Get-TagCategory APP_CODE) -ErrorAction SilentlyContinue
}

##### Executes tag assignment  #####
if (!(New-TagAssignment -Entity (Get-VM %%vmName%%) -Tag (Get-Tag $appCode) -ErrorAction SilentlyContinue)) { return $false } else { return $true }

##### Closes connection to vCenter  #####
Disconnect-VIServer * -Force -Confirm:$false

Custom action:

I am passing my vm tag as input attribute just to test the workflow. When i run the workflow, i can see  the logs where the input attribute replaces the variable in the powercli. But i keep encountering the error "The term '?' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again."

It seems to be a powercli related error but have verified each line and no "?" term exists here, I even replaced the script to exact same as pasted in the blog( with values pertaining to my environment) and still hit on the same error. If i am to hard code the varible values and run the powercli script, it runs perfectly fine.

Is there anything that i am missing. I am no javascript excpert. Appreciate any help on this.

i am pasting the logs here.
