SwissQRBill empty element StrdBkgInf (BillInformation)

I’m using SwissQRCodetext to create SwissQR code (Version 22.2.0).
If property BillInformation is not set (null) the QR code validation on https://validation.iso-payments.ch/ fails with remark: Das Element <StrdBkgInf> darf nicht leer sein, wenn dieses geliefert wird. Ausnahme: Wenn nachfolgende Elemente verwendet werden.

Code snippet to create the QR code:

        //create Swiss QR Bill
        SwissQRCodetext swissQRCode = new SwissQRCodetext();
        swissQRCode.Bill.Version = SwissQRBill.QrBillStandardVersion.V2_0;
        swissQRCode.Bill.Account = "CH4431999123000889012";
        swissQRCode.Bill.Amount = 1000.25m;
        swissQRCode.Bill.Currency = "CHF";
        swissQRCode.Bill.Reference = "210000000003139471430009017";
        swissQRCode.Bill.Creditor = new Address
            Name = "Muster & Söhne",
            Street = "Musterstrasse",
            HouseNo = "12b",
            PostalCode = "8200",
            Town = "Zürich",
            CountryCode = "CH"

        swissQRCode.Bill.Debtor = new Address
            Name = "Muster AG",
            Street = "Musterstrasse",
            HouseNo = "1",
            PostalCode = "3030",
            Town = "Bern",
            CountryCode = "CH"

        //encode Swiss QR Bill
        ComplexBarcodeGenerator generator = new ComplexBarcodeGenerator(swissQRCode);
        generator.Parameters.Barcode.XDimension.Pixels = 4;
        generator.Parameters.Barcode.QR.QrEncodeMode = QREncodeMode.ECIEncoding;
        generator.Parameters.Barcode.QR.QrECIEncoding = ECIEncodings.UTF8;
        string fileNmae = $"SwissQRBill-{Guid.NewGuid()}.png";

Thanks for the sample code and details.

I did test your scenario/case using your sample and found it generates the barcode Ok. Do you need Aspose.BarCode for .NET should throw an exception something like “Das Element darf nicht leer sein, wenn dieses geliefert wird. Ausnahme: Wenn nachfolgende Elemente verwendet werden” in english if BillInformation is not set, please confrim? After your confirmation, we will log appropriate ticket for evaluation/investigation.

Yes, I’m using Aspose.BarCode for .NET (current version 22.2.0). I explicit do not set property BillInformation, as you can see in my code sample. I don’t like to set any BillInformation. There is no exception when I generate the QR code.
Without BillInformation the StrdBkgInf element should not exists in the QR-Code. This is what the validation message basically explains in german.
If I set BillInformation property to a non emtpy string like
swissQRCode.Bill.BillInformation = "this text makes it valid";
everything works as expected and QR-Code validation passes without any hint or error.

I’ve added a running console application showing the issue
AsposeQrCodeSample.zip (1.5 MB)
