PPTX to PDF: "Comment by Nonexistent Author" Exception

Hi Team,

I am using Aspose Slides java to convert a PPT to PDF.
I am using below code to get all the Notes & Comments from PPT to PDF conversion.

INotesCommentsLayoutingOptions notesAndCommentsOptions = pdfOptions.getNotesCommentsLayouting();

If i am using comments only or Notes only the program works good.

However, when I use both Notes & Comments then getting below error.
Exception in thread “main” class com.aspose.slides.exceptions.Exception: Comment by nonexistent author. AuthorId = 77ccc0b8-3355-3dd6-e6c4-bb9573bc21c5.

Tried both windows 10 Enterprise & ubuntu 18.04.

below is my code

com.aspose.slides.Presentation presentation = new com.aspose.slides.Presentation(inFilePath);
com.aspose.slides.PdfOptions pdfOptions = new com.aspose.slides.PdfOptions();
com.aspose.slides.INotesCommentsLayoutingOptions notesAndCommentsOptions = pdfOptions.getNotesCommentsLayouting();
presentation.save(outFilePath, com.aspose.slides.SaveFormat.Pdf, pdfOptions);
