Hello,

We have problem with Viewer component because when we use View method on xlsx (we expect pdf on output), we receive exception:

   System.NullReferenceException: Object reference not set to an instance of an object.

It works fine on most files but not all.
This appear on .NET 6 with GroupDocs.Viewer for .NET 22.11 and 22.9.
Moreover on your demo page this document is also not showing.

Could you investigate this?
I am attaching the problematic file.

Unfortunately, I can’t reproduce this issue on my side using this sample-app.zip (48.8 KB). Can you please try running the app on your side or share your app.
