API Network Discovery

Following the instructions on GitHub (Discovery · solarwinds/OrionSDK Wiki · GitHub ) I am attempting to create a very basic network scan where IP address's between 10.X.0.1-10.X.31.254 are scanned with the credential ID's provided.   I am assuming the 3 separate plugin configuration are all actually part of the same script ?  Assuming this is correct, when I run the script now, the system is expecting an argument at the line below

#Error expecting argument

PS C:\Users\nsd000.QACMA> C:\Users\nsd000.QACMA\Documents\PowerShell Scripts\Do not Modify\Discovery.ps1

cmdlet Invoke-SwisVerb at command pipeline position 1

Supply values for the following parameters:

Arguments[0]:
