Troubleshooting
Lambda is missing required customer, invoice, receipt, or fiscal fields.
Lambda needs complete fiscal data before it can prepare a valid CFDI.
One or more required fields were empty, defaulted, or not supported by the incoming document. This can include customer tax data, payment method, payment date, receipt fields, line taxes, product codes, or currency.
Facturapi and SAT require complete fiscal fields. Lambda pauses instead of guessing values that should come from the invoice, payment, customer, or receipt context.
The note should name the missing field or group of fields. Lambda needs the actual value that belongs on the document, not a placeholder.
If the field is editable in Lambda review, complete it and continue. If the field must arrive with the source document, Lambda waits for the next received document with that value present.
