Troubleshooting

Precondition exceptions (NotaFiscal)​

File: Models/NotaFiscal.cs

NotaFiscal.Processar() throws InvalidOperationException when:

  • Emitente.RegimeTributario is NotDefined
  • Destinatario.ContribuinteIcms is NotDefined
  • TotalProdutosNF <= 0

How to fix:

  • Set nf.Emitente.RegimeTributario
  • Set nf.Destinatario.ContribuinteIcms
  • Set nf.TotalProdutosNF with the invoice total products amount (same base used for allocations)

Precondition exceptions (Produto)​

File: Models/Produto.cs

Produto.Processar() throws InvalidOperationException when:

  • PrecoUnitario <= 0
  • Quantidade <= 0
  • Cfop <= 0

How to fix:

  • Set item.PrecoUnitario, item.Quantidade, and item.Cfop

UF / interstate rate errors​

Files: Models/ImpostoMotor.cs, UFAliquotas/GradeAliquotasBase.cs

Common failures:

  • Origin/destination UF is blank when calling BuscarUFAliquota(...)
  • Destination UF not found in the table (KeyNotFoundException)

How to fix:

  • Ensure Emitente.UFSigla and Destinatario.UFSigla are set
  • If you use a rate file, ensure it contains UF=value for the desired destination UF
