SOAP Headers Unknown


I'm having a problem trying to execute a webmethod from a webreference.
The webservice is using basic authentication and i need to build the authentication header, i'm using an extension i found from OutSystems called EnhancedWebReferences version 5.0.2

I can't seem to make it work because i'm always getting an error saying that the AuthHeader is unknown.

Anybody, have an idea on how to build the soap header?

Just a minor update i'm using stack java.
