Hi Remzy,

I noticed this thread is the same as the one here: Value cannot be null parameter name: the context in Telerik Document Processing PdfProcessing - Telerik Forums. 

We can continue to discuss this there. If you re willing to share the documents that you are using I can convert this one to a support ticket which is a private thread. This way I will be able to determine what exactly is causing the exception. 

I am looking forward to your reply.
