Hello,
I'm using Angular Report Viewer and I'm getting the error as in attached image when I'm trying to load my report into the viewer using REST Web API service.
I can see in dev tools that the url that is failing is.
http://localhost:55504/api/report/clients/706df770722/parameters
and that the request payload is {report: "test.trdp", parameterValues: {EmployeeID: 31, Year: 2018}}.
This is happening in development environment. I'm using latest VS 2017 and Telerik Reporting 12.1.18.620
