Error re-saving an MPP file

Aspose.Tasks Product Family
1

Hi, I use a 30 day temporary license, when I open the attached file with Aspose and try to re-save it, I’m getting an Error. Not for all files, some file saving correct. I attach one of the problematic files.
testDoc.zip (113.5 KB)

Code:
FileInputStream prjStream = new FileInputStream(file);
Project project = new Project(prjStream);
project.save(to, SaveFileFormat.Mpp);

Error:
class com.aspose.tasks.private_.ms.System.ArgumentOutOfRangeException: startIndex + length cannot exceed length of string.

Can you explain what the problem is?

@s.afanasev.efso,
we examined the attached file and found that there is an error in our formula result calculation routine which results in the exception you observed.

We will fix the error in ver. 22.4 of Aspose.Tasks for .NET and in ver. 22.5 of Aspose.Tasks for Java.

P.S (2022.04.29): Edited incorrect versions (were 20.4 and 20.5).

The issues you have found earlier (filed as TASKSNET-10508) have been fixed in this update.
