Powerbuilder Classic calling webservice and get message "can not be reflected"

We are switching to Ultipro Saas offering, so I need to convert a program that synchronizes data to use Web Services instead of the direct DB connection we had before.

I created the proxy using .NET, but when I run authenticate I get the message "Method LoginService.Authenticate can not be reflected"

I'm not sure what I am doing wrong

li_ret = s_conn.createinstance(u_soap,"LoginService")

u_soap.setclientaccesskey( lws_client )

u_soap.setuseraccesskey( ls2_userkey )

u_soap.setusername( ls3_user )

u_soap.setpassword( ls1_pass )

u_soap.authenticate( ll_status, lb_status, ls_msg, ls_token )
