Hi All,
I am getting the Web response html from a web url which contains some angular tags and angular attributes (like _ngcontent-sc1="") in to it. So when I try to convert this angular tag and with attribute html into pdf using ASPOSE.PDF .net nuget from C# application it gives me error as below and if I remove those angular attributes (like _ngcontent-sc1="") it works well. Please help.

Error Details as below,
System.NullReferenceException: ‘Object reference not set to an instance of an object.’

Hi All,
I am trying to convert attached html into a PDF, but it is giving me error as a mentioned in current thread.
Below code I am using,
public void ConvertHTMLtoPDFAdvanced_WebPage()
{

		HtmlLoadOptions options = new HtmlLoadOptions()
        {
            PageInfo = { Width = 842, Height = 1191, IsLandscape = true },
            IsEmbedFonts = false
        };
		
		//FontRepository.Sources.Clear();
        FontRepository.Sources.Add(new Aspose.Pdf.Text.FolderFontSource(@"C:\Fonts\"));
        FontRepository.LoadFonts();

        Font font = FontRepository.FindFont("Knockout-HTF48-Featherweight");
		Document pdfDocument = new Document(@"C:\index.htm", options);
        
        pdfDocument.Save(@"C:\html_test.PDF");
	}

Please help. Even I tried supplying fonts too but that did not worked.
Please find attached html file along with fonts which I am converting to PDF.
