ArgumentOutOfRangeException error on Diagram.Save

Aspose.Diagram Product Family
1

Hello,
I’m encountering ArgumentOutOfRangeException while converting multipage Visio document.
Before you ask - I cannot send you the document , due to security reasons.
Document converts partially - only 2 out of 13 pages fail to convert. I’ve tried converting to several SaveFileFormat (png,jpeg,svg,html,pdf) and it’s always same 2 pages that fail.

Here some code context
var fileName = Path.GetFileNameWithoutExtension(filepath);
var savePath = filepath.Replace(Path.GetFileName(filepath) ?? throw new InvalidOperationException(), “”);
var diagram = new Diagram(filepath);
var pages = diagram.Pages;

            foreach (Page page in pages)
            {
                var pageDiagram = new Diagram();
                pageDiagram.Pages.Clear();
                pageDiagram.Pages.Add(page);
                var resultPathString = savePath + fileName + "-" + name + ".pdf";
                pageDiagram.Save(resultPathString, SaveFileFormat.PDF);
               }

Here’s error message occures specifically on pageDiagram.Save:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Aspose.Diagram Version 21.4.0.0

Is there a way to diagnose this on my side? All pages in document look similar , there’s nothing exceptional about those failing ones , at first glance at least

You may please make sure that you are using a valid license before using any method of the API. You can try using 30-days free temporary license in case you do not have one. Furthermore, it is necessary for us to test the scenario in our environment using the same files so that the issue can be addressed accordingly.

In case you cannot share your files publicly, you can send them in a private message by clicking over my username and pressing the Blue Message Button. We will test the scenario in our environment and address it accordingly.

Hello,
license is valid , works properly on all other files.
I cannot share document as it’s a document I am not authorized to share with third parties.
Is there maybe a loop to works through all shapes to find problem ones?
Any suggestions to find what’s causing failure at all?

Hello again,
I don’t know why you didn’t recommend to iterate through shapes manually, because it helped me to find problem ones.
figuresToFigureOut.zip (17.5 KB)
One of the shapes causes the ArgumentOutOfRangeException and the other one just ends up in wrong place.
Please report back if you will be able to replicate this error on your machines.
Thank you
