    I have a web app, in .Net Core 3.1 and I am using Telerik Reporting to generate my report. I am getting an error which says:
    "Failed to load resource: the server responded with a status of 500 (Internal Server Error) - api/reports/formats:1"


    I don't think the serviceUrl is the issue, but here it is:

    <script type="text/javascript">
            $(document).ready(function () {
                $("#btnReport").click(function () {
                    var viewer = $("#reportViewer1").data("telerik_ReportViewer");
                        report: "KarposhReports.Temp, KarposhReports, Version=, Culture=neutral, PublicKeyToken=null",
                        parameters: { imageUrl: $("#imageUrl").attr('href') }
                        serviceUrl: "/api/reports",
                        reportSource: {
                            report: "KarposhReports.Temp, KarposhReports, Version=, Culture=neutral, PublicKeyToken=null"
                        viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
                        scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
                        scale: 1.0,

                        ready: function () {

    Hi Zoran,

    This appears to be how the parameter is being passed to the Available Document Formats Endpoint. I recommend verifying that all of the Document Formats are available by navigating to the {web app domain}/api/reports/formats endpoint to ensure that the Reporting REST Service is up and running.

    In addition, I will need more information in order fully troubleshoot the issue. Can you provide the following information as well?

    1. The Reports Controller

    2. The Report Generation code, if any.

    Finally, I would also like to point to our ASP.NET Core Sample located in the default installation folder. See C:\Program Files (x86)\Progress\Telerik Reporting R1 2020\Examples\CSharp\Asp.NetCoreFullDemo for more information.

    In the meantime, please let me know if you have any additional questions. Thank you and I look forward to your reply.
