What output does the powershell program return, json? CC: @svisagan83

[piyush94]

The script is not returning anything. We assumed that in the result variable, the exit code of the script will be captured. Does it work this way or we have to explicitly return a value? Again main issue is that script is not getting executed if arguments are passed, even if nothing is returned. Also if we use named parameters like script.ps1 -appName "code", it throws below error:

Usage: dmtransfer [OPTIONS] [EXEC]... 

Try "dmtransfer --help" for help. 

Error: no such option: -a

[sbtaylor15]

Let me check on the passing back of the return code to the DM Script. I know that json output from the script is automatically parsed into DM Script variables.

[sbtaylor15]

The non-zero return code from the powershell script causes an exception to be thrown in the DMScript. This exception needs to be caught and transformed into a return code.

I am working on an example of how this should be structured.

script:

param (
    [Parameter(Mandatory=$true)]
    [string]$AppName
)

$app = Get-WmiObject -Class Win32_Product | Where-Object { 
    $_.Name -like $AppName
}

if($null -eq $app) {
    Write-Output "false"
    # exit 0
} else {
    Write-Output "true"
    # exit -1
}

@piyush94 - The latest image has the fix. Here are screen shots for configuring the Action.

param (
    [Parameter(Mandatory=$true)]
    [string]$AppName
)

$app = Get-WmiObject -Class Win32_Product | Where-Object {
    $_.Name -like $AppName
}

if($null -eq $app) {
        Write-Output "0"
    # exit 0
} else {
        Write-Output "1"
    # exit -1
}

@sbtaylor15 No luck, still not working.

param (
    [Parameter(Mandatory=$true)]
    [string]$AppName
)

$app = Get-WmiObject -Class Win32_Product | Where-Object { 
    $_.Name -like $AppName
}

if($null -eq $app) {
    Write-Output "false"
    # exit 0
} else {
    Write-Output "true"
    # exit -1
}

@sbtaylor15 Found a workaround: This is working.

CC: @svisagan83

[sbtaylor15]

@piyush94 - Added code to default the necessary command shell if one is not supplied.

.ps1 = powershell.exe -File .vbs = cscript.exe /nologo .js = cscript.exe /nologo .wsf = cscript.exe /nologo

CC: @svisagan83

[sbtaylor15]

@piyush94 - please remove your work around and let us know if the default is used.

[piyush94]

@sbtaylor15 Not working without workaround
