I solved it here : https://github.com/jsreport/jsreport-dotnet-example-webapp/issues/5#issuecomment-513762744

I know this is a common exception, but I haven't found any solution for it, am using a mac and I installed this library dotnet add package jsreport.Binary.OSX --version 2.5.0 with this example jsreport-dotnet-example-webapp , provided on github but no luck I just get the exception below. What could I be missing ?

Jsreport.Local.JsReportBinaryException: Error rendering report: 
   at jsreport.Local.Internal.LocalUtilityReportingService.RenderAsync(String requestString, CancellationToken ct)
   at jsreport.AspNetCore.JsReportMiddleware.Invoke(HttpContext context)
   at Microsoft.AspNetCore.Mvc.Internal.ResourceInvoker.InvokeNextResourceFilter()
   at Microsoft.AspNetCore.Mvc.Internal.ResourceInvoker.Rethrow(ResourceExecutedContext context)
   at Microsoft.AspNetCore.Mvc.Internal.ResourceInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted)

I will be very grateful with the help.
