Aspose.HTML Product Family

Referencing a SVG image using the current latest version, 23.10, causes:
System.NullReferenceException: ‘Object reference not set to an instance of an object.’

    private static void NullReferenceException()
    {
        const string html = "<html><body><img src='https://logincdn.msauth.net/shared/1.0/content/images/backgrounds/2_bc3d32a696895f78c19df6c717586a5d.svg' /></body></html>";

        using (var document = new Aspose.Html.HTMLDocument(html, "."))
            Aspose.Html.Converters.Converter.ConvertHTML(document, new PdfSaveOptions(), "out.pdf");
    }

We were unable to reproduce the NRE in our environment while testing with 23.10 version of the API. Can you please share some more details like your environment information and complete stack trace?

Hi, here is the stack trace, it looks like the error is related to interacting with the hosting site as downloading the SVG and referencing it from the file system works.
