B2C offline invoices not getting reported to ZATCA

We have clients facing an issue where the B2C invoices not getting reported to ZATCA.

“errors”: [
{
“type”: “ERROR”,
“category”: “Duplicate-Invoice”,
“errorCode”: “Invoice-Errors”,
“errorMessage”: “Invoice was already reported successfully earlier.” ,
“errorSource”: “ZATCA”

We checked with the invoices; these are not reported to ZATCA

@Joseph you need to investigate further and deeper. There were many similar instances raised by other members but when their sample hashes were checked, the initial response of 200 / 202 was already found at ZATCA’s side every single time. May be there was issue in saving the response from your end, in such case please treat 409 as “Successfully Reported” and system should stop re-trying the same XML again.
