Hi
We have a solution where we in our .Net API use Aspose to generate dynamic reports, where our customers define a Word template which we then populate with data, converts to PDF, and then return the PDFdocument.
This works fine 99.9% of the time.
But today, registered for the third time in 3-6 months suddenly it breaks, and every function in the API creating a PDF from Docx is broken.
Restarting the API fixes the error, and all is good again.
It is not easy to recreate in a sample application as we have no idea to what happens or is causing this.
We get this stacktrace from our application.
System.ArgumentException: The namespace declaration attribute has an incorrect ‘namespaceURI’: ‘A Namespace Name for xmlns Attributes’.

In this case we just seem to call Aspose.Pdf.Document.Save() and not much more.
We are running in production with Apose 21.12 at the moment.
Is this a known bug that you have fixed in the last year. Or is this new to you. Or are we doing something wrong?
I hope you are able to provide some feedback though I am fully aware that we have very little information to start from.
Best regards
