VSS file after conversion to PDF is blank when opened

Hi
After converting a VSS file to PDF using Aspose Diagram API for Java,when opened the PDF file, it is blank.

The code used to convert is

import com.aspose.diagram.Diagram;
import com.aspose.diagram.SaveFileFormat;

   String filePath = "D:\\testpdf\\PR000188_001.vss";
   String cfilePath = "D:\\testpdf1\\PR000188_001.pdf";



	Diagram diagram;
	try {
		diagram = new Diagram(filePath);
		diagram.save(cfilePath, SaveFileFormat.PDF);
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

Used the Aspose Diagram 23.7 jar

Uploading the vss file having the issue.

file.zip (17.9 KB)

Can you suggest a resolution?

Thanks
Rama

Thanks for the vss file.
This is a template file and no pages have been added yet. Even when saved as PDF using MS Visio, the resulting pdf file remains empty too.
Please add pages to the diagram,Thanks.
