NullReferenceException while converting PPTX


I'm getting a 'NullReferenceException' after trying to convert .pptx file like this:

            using (var presentation = Presentation.Open(sourcePath))


                presentation.ChartToImageConverter = new ChartToImageConverter();

                presentation.ChartToImageConverter.ScalingMode = ScalingMode.Best;

                PresentationToPdfConverterSettings settings = new PresentationToPdfConverterSettings();

                using (var pdfDoc = PresentationToPdfConverter.Convert(presentation, settings))


                    pdfDoc.EnableMemoryOptimization = false;






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