Here is the script step of the action:

(function execute(inputs, outputs) {

  try { 
 var r = new sn_ws.RESTMessageV2('Okta', 'Create User');
 r.setStringParameterNoEscape('lastName', inputs.lastName);
 r.setStringParameterNoEscape('password', inputs.password);
 r.setStringParameterNoEscape('email', inputs.email);
 r.setStringParameterNoEscape('firstName', inputs.firstName);
 r.setStringParameterNoEscape('login', inputs.login);
 var response = r.execute();
 outputs.httpStatus = response.getStatusCode();
 outputs.responseBody = response.getBody();
}
catch(ex) {
 var message = ex.message;
}
  
})(inputs, outputs);

And here is the output variables

And now that I'm posting this I think I see the problem.... My code uses the capitalization in the label.  Is the label what I should be using in the code?  OR should I be using the name which doesnt have the capitalization?
