Simplified Invoice Debit Invoice QR Invalid

XML and business rules
1

I have set up a simulation account to test the ZATCA phase II verification. Steps I performed:

  1. Create a CSR successfully
  2. Send to the simulation compliance Api successfully
  3. Create and sign Standard Invoice, Debit & Credit successfully.
  4. Create and sign a Simplified Invoice, and Credit successfully
  5. Simplified Debit Invoice (Invalid QR code format error coming continuously)

Can anyone help me, please? What is the mistake I’m making?
