When I try to sign an invoice with withholding tax and IVA tax, I get the next error:

PAC no firmó el CFDI:

• Código: CFDI40999 - Error no clasificado.
• Mensaje: The required attribute 'Impuesto' is missing.

But when I try to sign an invoice with only IVA tax, the invoice signature is correct.

I have the localization for México and all modules are up to date.

Does anyone know how to correct this error?
