Hello Alana,

Yes, you are right. AHVALUEDRIFTED has to be a boolean value. The name implies it actually but I did not connect the dots.

Thank you for the help!

Hello,

I'm evaluating Otter Version 2023.6 (Build 2).
I'm trying to write a remediating drift powershell script:

<# 
.DESCRIPTION
This script ensures that the specified environment variable is set to the desired value.

.PARAMETER EnvironmentVariableName
Environment variable name.

.PARAMETER EnvironmentVariableValue
Desired value for the environment variable.

.AHEXECMODE 
$ExecutionMode

.AHDESIREDVALUE 
$EnvironmentVariableDesiredValue

.AHCURRENTVALUE 
$EnvironmentVariableCurrentValue

.AHVALUEDRIFTED
$EnvironmentVariableDriftedValue
#>

param ([string]$EnvironmentVariableName, [string]$EnvironmentVariableValue)

$EnvironmentVariableDesiredValue = $EnvironmentVariableValue
$EnvironmentVariableCurrentValue = [System.Environment]::GetEnvironmentVariable($EnvironmentVariableName, [System.EnvironmentVariableTarget]::Machine)

Write-Host "Current value of environment variable '$EnvironmentVariableName' is '$EnvironmentVariableCurrentValue'."

if ($ExecutionMode -eq "Collect") {
  if ($EnvironmentVariableValue -ne $EnvironmentVariableCurrentValue) {
    Write-Information "Environment variable '$EnvironmentVariableName' has drifted from the desired value."
    $EnvironmentVariableDriftedValue = $EnvironmentVariableCurrentValue
    return $false
  } 
  else {
    Write-Information "Environment variable '$EnvironmentVariableName' is set to the desired value."
    return $true
  }
} 
  
elseif ($ExecutionMode -eq "Configure") {     
  if ($EnvironmentVariableValue -ne $EnvironmentVariableCurrentValue) {
    [System.Environment]::SetEnvironmentVariable($EnvironmentVariableName, $EnvironmentVariableValue, [System.EnvironmentVariableTarget]::Machine)
    Write-Information "Environment variable '$EnvironmentVariableName' has been set to the desired value."

  } 
  else {
    Write-Information "Environment variable '$EnvironmentVariableName' is set to the desired value."
  }
}   

When this script is executed on a server it fails with following error:

I would like to add that when I removed all augmented help metadata then this script would run with no issues.

Can you tell me what is the problem?
