وعليكم السلام  
This error indicates that the hash value embedded in the QR code (stored in the EmbeddedDocumentBinaryObject under cac:AdditionalDocumentReference with cbc:ID = “QR”) does not match the actual hash of the XML invoice content after applying the required transformations. ZATCA requires the QR code to contain a Base64-encoded TLV (Tag-Length-Value) structure that includes the hash of the canonicalized invoice XML

@aman please check below posts:

The error received from the web-based validator is related to the signature error category, which is due to the difference between the X.509 certificate (PCSID) that you have signed your simplified e-invoice with and the x.509 certificate that is being used in the validation.

The web-based validator has a default certificate in the back-end which differs from the one that you obtained during the API onboarding process, so receiving a signature error while validating a signed simplified tax e-invoice using the web-based validator is a normal behavior, so please don’t worry about this specific error & rely on the API response

> Dear Moainatour validating Simplified Invoice on web-based validator will always show signature error as web validator validates using a certificate different from the one used for signing Simplified Invoice. Therefore, validating Simplified Invoice using web-based validator will give a certificate validation error which is an expected behavior. As you are aware, Simplified Invoices are not required to be shared in XML format with customer, therefore, customers are not expected to validate Simp…

Have you used Fatoora to sign the invoice? I don’t think so.
