Boa tarde pessoal

Eu tenho o seguinte código ADVPL:

#include "Totvs.ch"

    oWSDL:cprocessId         := "solicitud_vacaciones" //solicitud de vacaciones
    oWSDL:nchoosedState        := 4 //inicio

    oWSDL:ccomments         := "Solictud de vacaciones via ERP"

    oWSDL:lmanagerMode := .T. //como gestor del proceso es .T.

    varinfo( "", oWSDL )

Estou tentando consumir um serviço do webdesk / ECMWorkflowEngineService? Wsdl

Ao executar a fonte, ele tenta iniciar o processo, mas retorna o seguinte:

2020-10-01 12:40:34,240 INFO [com.totvs.technology.ecm.workflow.ws.WorkflowEngineService] (default task-401) Inicio de startProcess() iniciado... 2020-10-01 12:40:34,242 INFO [org.apache.cxf.phase.PhaseInterceptorChain] (default task-401) Application {http://ws.workflow.ecm.technology.totvs.com/}ECMWorkflowEngineServiceService#{http://ws.workflow.ecm.technology.totvs.com/}startProcess has thrown exception, unwinding now: java.lang.Exception: Campo cardData no tiene el campo y/o valor

indica que o campo cardData não possui o campo e / ou valor, Estou usando oWSDL: oWSstartProcesscardData para preencher as informações de cardData, mas não consigo preencher os campos do formulário. Alguém tem um exemplo de como iniciar um processo do fluig no protheus en Advpl?

Agradeço a ajuda.
