KeyNotFoundException when loading the file

Aspose.Note Product Family

Hello dear Aspose team,

We noticed that Aspose.Note is throwing KeyNotFoundException when loading the following file (with Aspose.Note 23.11)

We get the following stack trace when loading the file

Type:
System.Collections.Generic.KeyNotFoundException

Message:
The given key was not present in the dictionary.

StackTrace:

at Aspose.Note.Document…ctor(Stream inStream, LoadOptions loadOptions)
at Aspose.Note.Document…ctor(Stream inStream)
at LoadFile(Filespec filespec, LoadOptions options, FileAccess access, AppError& error)

Can you please check if this is a bug in the library itself?

Best, Vahe.

I’m getting this exception while converting onenote document to pdf on the below code, please resolve this issue:

public List TransformOneNoteFileToPdfStream(byte[] documentBytes)
{
var pdfContent = new MemoryStream();
var license = new License();
license.SetLicense(“Aspose.Note.NET.lic”);
var document = new Document(new MemoryStream(documentBytes));
var pdfDocuments = new List();
IList pages = document.GetChildNodes();
for (int i = 0; i < pages.Count(); i++)
{
PdfSaveOptions opts = new PdfSaveOptions();
opts.PageIndex = i;
opts.PageCount = 1;
document.Save(pdfContent, opts);
pdfDocuments.Add(new OneNoteConvertedFileDto
{
PageTitle = pages[i].Title?.TitleText.Text,
File = pdfContent,
PageIndex = i + 1
});
pdfContent = new MemoryStream();
}
return pdfDocuments.Count() > 0 ? pdfDocuments : null;
}

I have attached onenote file for your reference:
response.zip (70.2 KB)

@pdhakal,

Which version of Aspose.Note for .NET you are using? Please try using Aspose.Note for .NET 24.9. I have tested using the following line of code with Aspose.Note for .NET 24.9 and it works fine.
e.g.,

var document = new Document("e:\\test2\\response.one");

Let us know with details if you still find the issue with Aspose.Note for .NET 24.9.
