ODP to PPTX - Errors but an empty file arrives

When converting two files from ODP to PPTX, errors appear, but a file arrives that is 0 bytes in size.

Using - aspose-slides-20.5-jdk16.jar

Using this code:
com.aspose.slides.Presentation presentation = new com.aspose.slides.Presentation(inputPath);
presentation.save(outputPath, com.aspose.slides.SaveFormat.Pptx);

Here are the errors:
image.png (9.1 KB)

Here are the before and after files:
odp2pptx.zip (1.1 MB)


I have worked with the presentation file and have been able to observe the issue. A ticket with ID SLIDESJAVA-38143 has been created to further investigate and resolve the issue. We will share good news with you as soon as the issue will be addressed.
