Hi pramodnaik,
Could you output the contents of the variables you are using? Please obfuscate any information you don't want to be seen publicly. If you could run the output with the Format-List * option as well please.
You can also probably limit this to just the parameter that is having issues if you look at the error. The variable that is causing a problem with be underscored with "~" symbols and this is the one that would be interesting to see the output from.
Cannot validate argument on parameter 'id'
This is indicating that the cmdlet is having issues with what is being passed to it. Its strange because Id is a readonly attribute of the objects but this might be a wrong lead to follow. The output of your variables should help... maybe...
Kind regards.
