Dear support team,
I'm using Report server (Version: 6.0.20.219) to design and manage report.

After completed design report I follow this link "https://docs.telerik.com/reporting/html5-report-viewer-howto-use-it-with-reportserver" to  embed report into my ASP.NET Application.

I follow step by step is completed, but when I run that html report it show error:

"Error loading the report viewer's templates. (templateUrl = 'http://localhost:83/api/reports/resources/templates/telerikReportViewerTemplate-14.0.20.219.html/')."

I come in to Report Server installed folder "C:\Program Files (x86)\Progress\Telerik Report Server\Telerik.ReportServer.Web\ReportViewer" but I can't find the "templates" folder :(

Please help me the way to fix it.

Hello,

The viewer's HTML template is served from the server thought the Report Server API, it is not fetched from the local files. Error loading the report viewer's templates indicates that the reportServer's url property is empty or invalid. Make sure that the address of the Report Server is correct, for example:

$("#reportViewer1")
  .telerik_ReportViewer({
    reportServer: {
      url: "http://yourReportServerUrl:port",
      username: null,
      password: null
    },
    //templateUrl: '/ReportViewer/templates/telerikReportViewerTemplate-x.x.xx.xxx.html',
    reportSource: {
      // The report value should contain the Category and ReportName in the following format
      // {Category/ReportName}
      report: "Samples/Dashboard"
        parameters: {
          ReportYear: 2004
        }
      }
  });
