  • Maniero, also do not have much traceability on the error, for having recovered from it through a generated Cod on the screen.

  • By the exception message, one only has the information that the method DocumentoUploadPendenciaBusiness.ObtemTokenAutenticacaoMorpheus(Int32 numSeqCorretor, String nomeCorretor) has released an exception in C: Pcacodegit Metlife.Cotadorux Metlife.Cotador.Business Documenteploadpendenciabusiness.Cs, line 242.
