Hi Malik,

We have successfully generated the CSR and Private Key, and we were also able to sign the invoice XML successfully.

However, we are encountering an error while validating the signed invoice using the EInvoiceValidator.ValidateEInvoice() method. Please note that the same signed invoice is being successfully validated when using the .NET SDK v.DotNet-238-R3.4.5 via the command line, but it fails when validated programmatically through code.

below is the XML we are trying to validate using default PIH and CSR.

```auto
