Convert HTML to PDFA using Aspose.PDF for .NET fails with NullReferenceException

Aspose.PDF Product Family

Hi,

We are converting next html file IMDb - Movies.zip (29.9 KB) to pdf using Aspose.Pdf 17.9.

We use the following code for conversion

var htmlLoadOptions = new Aspose.Pdf.HtmlLoadOptions();
var pdf = new Aspose.Pdf.Document(inputFilePath, htmlLoadOptions);

pdf.Convert(
    new MemoryStream(),
    PdfFormat.v_1_5,
    ConvertErrorAction.Delete);

pdf.Save(outputFilePath);

The constructor of Aspose.Pdf.Document throws an exception

System.NullReferenceException: Object reference not set to an instance of an object.
