Hi,
I try to show the report in mvc by place viewer in the Razor viewer with StiMvcViewer.
When user try to view the report, the report is shown but one error has been occurred:
Failed to load resource: the server responded with a status of 404 (Not Found) undefined:1
This error has been appear in console chrome log.
When I clicked on this error, undefined object is displayed in "Image" categories with this address: "hxxp://localhost:14106/undefined" (DevTools -> Application Tab)
Undefined object is displayed in Network Tab, too and when click on Initiator column value, below JavaScript code is displayed:
