Hi,
I was testing the sample code provided in the following article published on the documentation site the Link is HERE
The sample code in this article was working perfectly on Groupdocs viewer version 2.14
when upgrading to version 2.16 the code stopped working and calling the HTTP Handler named
"ViewDocumentHandler " returns the following error as ASP.NET Error Page:
Document path cannot be null, empty or contain only whitespaces
please advice about this as soon as possible
