@michoel super appreciate the help. We are using RESTlets to connect, and not the SOAP connector, so we have to set up the Oauth 1.0 by hand (not supported by Talend). We finally did get it to connect following this info : http://blog.prolecto.com/2017/11/11/download-a-java-application-to-connect-to-netsuite-oauth-tba-restlet-endpoints/ and moving the non functional stub into a module. Not sure if it's called a "module" or something else because I'm not a Talend dev, but we wrote it up in a different module/area and sourced it in.
