Getting Sql Connection Error while rendering the Telerik Report in ,net Core App

[shabeer]

Hi Friends,

 I am unable to render the  Telerik Report in the .net core App.

          ReportSource report = new InvoiceTest(); //calling from the dll
                    report.Parameters.Add("id", 1);
                    report.Parameters.Add("UserId", invoice.userId);
                
                    RenderingResult result  = reportProcessor.RenderReport("PDF", report,null);

                    if (!result.HasErrors)
                    {
                        string fileName = result.DocumentName + "." + result.Extension;
                        string path = System.IO.Path.GetTempPath();
                        string filePath = System.IO.Path.Combine(path, fileName);

                        using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
                        {
                            fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
                        }
                    }

My error message like :

InnerException = {"Format of the initialization string does not conform to specification starting at index 0."}

your help on this would be greatly appreciated

The "Format of the initialization string does not conform to specification starting at index 0" error can be caused by a missing or invalid connection string. Double-check if the connection string(s), used by the report's SqlDataSource component(s), is(are) copied in the application's configuration file(appsettings.json/app.config).

Also, test the connection string in a SQL management tool to ensure that it is correct.
