When I run my .net core app locally, via Visual Studio the reports work fine. They are generated like they are supposed to
but when I host the app on a server, nothing happens. I don't even get a console error or a warning.

This is my ConfigureServices in the Startup

public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<IISServerOptions>(options =>
            {
                options.AllowSynchronousIO = true;
            });
            services.AddRazorPages().AddNewtonsoftJson();
            // Configure dependencies for ReportsController.
            services.TryAddSingleton<IReportServiceConfiguration>(sp =>
                new ReportServiceConfiguration
                {
                    ReportingEngineConfiguration = ConfigurationHelper.ResolveConfiguration(sp.GetService<IWebHostEnvironment>()),
                    HostAppId = "KarposReports",
                    Storage = new FileStorage(),
                    ReportSourceResolver = new UriReportSourceResolver(
                        System.IO.Path.Combine(sp.GetService<IWebHostEnvironment>().WebRootPath, "ReportTemplate"))
                });
            services.AddCors(o => o.AddDefaultPolicy(builder =>
            {
                builder
                    .WithOrigins("http://localhost:60024", "https://app.gdi.mk/", "Access-Control-Allow-Credentials")
                    .AllowAnyOrigin()
                    .AllowAnyMethod()
                    .AllowAnyHeader();
            }));
            services.AddControllersWithViews();
        }

 

Here is the view, where my ReportViewer is. I tried with the standard serviceUrl variations "/api/reports" as well as "api/reports" as well as "~/api/reports".

I have no errors in console, in the picture attached.

Anyone has any idea why would it generate the reports just fine locally via Visual Studio and when I host the app it doesn't generate /print the reports?

Hi Zoran,

Thank you for responding to support ticket 1475159. I wanted to put the response here for the community when trying to host their reporting applications as well.

This specific issue is due to the hosting configuration in IIS. Let me provide more details below. 

IIS Hosting Concepts

There are a couple of website hosting concepts used in IIS. These are Sites, Applications and Virtual Directories. For details on these see the Microsoft IIS documentation. Although, I would like to review the issue related to the report viewer below.

From the provided screenshot, I can see that the application was hosted under the default IIS website in a folder named karposreports. This results in a route format of hostname/foldername for each application or folder under the site. In this case it is https://localhost/karposreports.

This is one way a single server can host multiple web applications. However, the important concept is that the script references and the report viewer both need to include the application name or folder name in the URL to resolve properly. 

To elaborate, this will work by prepending karposreports to the src property of the script references and the serviceUrl of the report viewer initialization code. This will resolve the route to the correct application. See the following examples.

Script References

<!--If Kendo is used it should be added before the report viewer.-->
<script src="/karposreports/Reports/telerikReportViewer-14.1.20.513.min.js"></script>
<script src="/karposreports/Reports/telerikReportViewer.kendo-14.1.20.513.min.js"></script>

Report Viewer Initialization

$("#reportViewer1").telerik_ReportViewer({

    serviceUrl: "/karposreports/api/reports/",
    reportSource: {
        report: documentType,
        parameters: mainReportParameters
    },
    viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
    scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
    scale: 1.0,
    enableAccessibility: true,
    sendEmail: { enabled: false },
    ready: function () {
        //this.refreshReport();
    },
});

Please let me know if you need any additional information. Thank you for using the Telerik Reporting forums.
