Getting Error "Object reference not set to an instance" while calling Pipeline.Invoke()

Question

Hi,

I am trying to execute get subscription using get-msolaccountsku. I am executing this script in .Net core application. Getting "Object reference not set to an instance of an object" error. Please help to resolve this.

        var scr = @"$username = '" + uName + @"'  

$password = ConvertTo-SecureString '" + Pwd + @"' -AsPlainText -Force
$creds = New-Object System.Management.Automation.PSCredential -ArgumentList ($username, $password)
Connect-MsolService -Credential $creds
$getAzACC = Get-MsolAccountSku
$getAzACC";

        Runspace runspace = RunspaceFactory.CreateRunspace();  
        Runspace.DefaultRunspace = runspace;  
        runspace.Open();  
        StringBuilder stringBuilder = new StringBuilder();  
         

        var powershell = PowerShell.Create();  
         
        powershell.Commands.AddScript(scr);  

        Collection<PSObject> results1 = powershell.Invoke();  
        //runspace.Close(); // Really should be in a finally block  
        foreach (PSObject obj in results1)  
        {  
            stringBuilder.AppendLine(obj.ToString());  
        }  

This is code i am working. Getting "Object reference error" while executing Pipeline.Invoke.
