Inquiry Regarding an Error During Invoice Signing

We would like to inform you that we have successfully integrated one of our Customer with the Zakat, Tax, and Customs Authority. The Customer’s private key and certificate were generated, and after obtaining the OTP, the Temporary Compliance was successfully completed.

After retrieving the Temporary Compliance, we requested the Final Compliance. However, the response from the API indicated that six invoices must be Checked to obtain the Final Compliance, which is an expected procedure.

However, during the invoice Checked process, we encountered the following error:
[Error] Generating EInvoice QR

This error occurs when signing the XML file in the following code:
SignResult objResultSignDocument = eInvoiceSigner.SignDocument(xmlDocument, certificateContent, privateKeyContent);

We have previously integrated multiple Customers and have not faced this issue before. We would appreciate it if you could clarify the cause of this error and whether there are any additional requirements or updates that we need to consider.

For your reference, the integration was done with the Simulation Platform.
