We're facing an issue that we can't quite solve. We have integrated the Web Report Designer into our ASP.NET Framework 4.8 project and it's work a treat when running it on my machine under IIS. We tried to publish it onto our live server, but we get an error code 500.
The ASPX page:
<%@ Page Language="c#" CodeBehind="TelerikReportDesigner.aspx.cs" AutoEventWireup="True" Inherits="Traxs.ASPX.TelerikReportDesigner" %>
<!DOCTYPE html>
<html>
<head>
<title>Report Designer</title>

<div id="webReportDesigner">Loading...</div>
<script type="text/javascript">
$(function () {
$("#webReportDesigner").telerik_WebReportDesigner({
persistSession: false,
toolboxArea: {
layout: "list"
},
serviceUrl: "../api/reportdesigner"
});
});
</script>
</body>
</html>
The controller:
[Route("api/reportdesigner")]
public class ReportDesignerController : ReportDesignerControllerBase
{
static ReportServiceConfiguration _configurationInstance;
static ReportDesignerServiceConfiguration _designerConfigurationInstance;
static ReportDesignerController()
{
var path = Path.Combine(HttpContext.Current.Server.MapPath("~"), "TelerikReportDesigner/Reports");
var resolver = new UriReportSourceResolver(path)
.AddFallbackResolver(new TypeReportSourceResolver());
_configurationInstance = new ReportServiceConfiguration
{
HostAppId = "Html5App",
Storage = new FileStorage(),
ReportSourceResolver = resolver,
ReportSharingTimeout = 0,
ClientSessionTimeout = 20
};
string sessionId = HttpContext.Current.Request["ASP.NET_SessionId"];
_designerConfigurationInstance = new ReportDesignerServiceConfiguration
{
DefinitionStorage = new DatabaseDefinitionStorage(path, sessionId),
ResourceStorage = new DatabaseResourceStorage(),
SettingsStorage = new DatabaseSettingsStorage()
};
}
public ReportDesignerController()
{
this.ReportServiceConfiguration = _configurationInstance;
this.ReportDesignerServiceConfiguration = _designerConfigurationInstance;
}
}
The log generated by Fiddler Jam.

I found the issue, some logic threw an exception in DatabaseSettingsStorage, which was instantiated in the ReportDesignerController constructor.
