Basically I am trying to add the client certificate for authentication, using integration activity.

As per https://www.netiq.com/documentation/...efactions.html .When I try to add WS Interchange Action, with below steps:

Right-click the line in the action model that is one line above the position in which you want to place the WS Interchange action (the new action is inserted below the line that you selected).
Select New Action > Data Exchange > WS Interchange.

it's giving me error message: cannot create WSDL service : Index out of bound.

Can anyone please help me on this.
