Return code for Powershell script from vCO

Hello,

I have been trying to get the return code of a Powershell script executed from vCO using the plugin. I can capture the output but I would like to get the script exit code (as specified by an exit statement on the PS script).

Here is my vCO code:

try {
    session = psHost.openSession();
    var script =  '& "' + externalScript + '" ' + arguments;
    result = session.invokeScript(script);
    if (result.invocationState  == 'Failed'){
        throw "PowerShellInvocationError: Errors found while executing script \n"  + result.getErrors();
    }
    //Show result
    var psOutput = result.getHostOutput();
    var psErrors = result.getErrors();
    var psResults = result.getResults();
    System.log("Output:"+psOutput);
    System.log("Errors:"+psErrors);
    System.log("Results:"+psResults);
} finally {
    if (session){
        psHost.closeSession(session.getSessionId());
    }
}

As I mentioned psOutput works fine and contains the std output, but I always get an empty string for psErrors and a NULL value for psResults, even when I change my script to deliberately exit with an error code different than 0.

Anybody has the exit code working?

Thanks,

Juan.
