Chart causing workbook.Save to fail with Null Error

Hello,

Our customer is having an issue with the attached report. We were able to trim this down to a single chart causing the failure. When we try to save this file using workbook.Save() the method throws an Object not set to an instance or reference error. This can be reproduced by simply opening and trying to save the file with aspose.

Workbook workbook = new Workbook(path);
workbook.Save(savePath); // <-- Fails
