Not being able to get updated value after process run

a!startProcess(
    processModel: cons!CE_GERAR_PIX,
    processParameters: {
      token: local!token,
      idSolicitacao: ri!idSolicitacao,
      valorPrevisto: local!value_for_payment,
      fileHistoricoContrib: local!uploaded_contrib_history_file[1],
      result: null
    },
    onSuccess: a!save(
      local!test, fv!processInfo.pv
    )
)

The result is not being updated from process model

As it's a portal, I can't use a form inside the process model. At the Output, as you can see, the result is being stored. The process instance stores the variable, but it doesn't load the `Result` for the interface

The instance:

So what should I do to accomplish it? Any documentation into that? the interface onSuccess calling doesn't fully load the values I am expecting
