InvalidOperationException when opening specific DotX files


the following code throws InvalidOperationException when opening the attached DOTX files.

var doc = new Document(inputStream);
var info = doc.GetPageInfo(0);

Here are the exception details:
- Exception thrown: ‘System.InvalidOperationException’ in Aspose.Words.dll
- Additional information: "This operation requires the node to be inside the main document."

tested with Aspose.Words.dll for .NET version 17.5

After getting the page information I expect to be able to render these documents.

Best Regards,
