Error after publishing the report on the server

[TrueSteps]

When I execute the report locally, it executes well. But when we published it on the web the report shows the followed error "Error registering the viewer with the service. An error has occurred.Object reference not set to an instance of an object."

Code snippets:

var viewer = $("#smsReportViewer").telerik_ReportViewer({

                          serviceUrl: "/api/reports/",

                          reportSource: {

                              report: "SMSWebClient.Reports.AccountsReport1, SMSWebClient, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null",

                              parameters: params

                          },

                          viewMode: telerikReportViewer.ViewModes.PRINT_PREVIEW,

                          scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,

                          scale: 1.0,

                          ready: function () {

                              $("#smsReportViewer").css("height", $(document).height() - 200)

                              checkResizeNeeded();

                          },

                      });

 

Below, the Stack trace

Kindly note that we tried the following (via web config and webapi caching overrides):
- used file based caching
- used memory based caching
- used IsolatedMode in caching

And also reset the security permissions for app pool user and still same issue occurs.

I attached the error message

Hello TS,

I believe this issue is related to the one described in a support ticket#1047757 opened by you so we can continue our discussion in the ticket.

For other community members, interested in this topic below is the reply from the support ticket:

"This error means that the REST Service might not be implemented correctly or is not found by the report viewer client. 
Please review How To: Use HTML5 ASP.NET MVC Report Viewer in an application and How To: Add Telerik Reporting REST Web API to Web Application help articles and check if everything is implemented correctly on your end.

You can also find sample implementations of the viewer and the service in the Telerik Examples folder: <installation folder>\Telerik\Reporting <version>\Examples"
