PowerShell Logging / Error Handling

Hi All!

So I am trying to create a PowerShell step in PDQ and I am having a hard time with the output log. Here is a sample of my code.

Write-Output "Starting Script" # I have tried Echo's instead as well
Try {
    [XML]$Output = .\BiosConfigUtility64.exe /getvalue:"TPM Device"
    $TMPDevice = Select-Xml -Xml $Output -XPath "//VALUE" | foreach {$_.node.InnerXML}
    IF ($TMPDevice -eq "<![CDATA[*Hidden,Available]]>")
    {
        Write-Output  "Enabling TPM Device"
            .\BiosConfigUtility64.exe /cpwdfile:default_password.bin /setvalue:"TPM Device","Available"  
    }ELSE{
        Write-Output  "TPM Device is Available"
    }
}Catch {
    $_.Exception #I have also tried just $_
    exit 6
}

Ultimately I understand the exe command on line 8 is causing the exception but I am trying to understand how to handle this properly.

I guess I am not asking how to fix the exe exception and trying to figure out how to get data into my output.log. No matter what output type or error type I use I do not get any output log. I would hope to at least see "Starting Script"

For this script I would like to see the following in the Output Log.

Starting Script
Enabling TPM Device
<BIOSCONFIG Version="" Computername="#######" Date="2020/05/14" Time="23:42:16" UTC="20">
        <SUCCESS msg="Successfully read password from file" />
        <SETTING changeStatus="fail" name="TPM State" returnCode="4">
                <OLDVALUE><![CDATA[Disable]]></OLDVALUE>
                <VALUE><![CDATA[]]></VALUE>
        </SETTING>
        <ERROR msg="An operation failed" />
        <ERROR msg="BCU return value" real="4" translated="4" />
</BIOSCONFIG>
#and maybe some exception code down here for $_ 

Is what I am looking for even possible? I just find error handling hard in PDQ. Once I write my PowerShell our deployment users may not understand the errors and how to move forward. This way I can enter my own error handling and they can see in plain text what broke and what needs to be done manually.

Any help would be great.

Thanks!
