I cannot get it working and the linked sample application crashes on line 10 of Index.cshtml
The two files are being created correctly, but instead of the PDF being displayed in a new tab, a tab opens with an error:
"The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Pictogram(Int32)' in 'Project.Controllers.MyController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters"
Pictogram is the View that that the diagram is shown on.
