I am trying to use NancyFX (clint-eastwood) with dotnetcore1.1 and dotnet-cli 1.0.0-rc4-004771. My current project structure is -
CustomBootstrapper.cs
HomeModule.cs
index.sshtml
nancyapp.csproj
Program.cs
Startup.cs
And codes are -
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.Owin">

<PackageReference Include="Microsoft.AspNetCore.Server.Kestrel">
<Version>1.1.0</Version>
</PackageReference>
<PackageReference Include="Nancy">
<Version>2.0.0-clinteastwood</Version>
</PackageReference>
</ItemGroup>
</Project>

Welcome to Nancy App.

CustomBootstrapper.cs is currently empty.
When I try to access Get("/test/{name}", args => new Person() { Name = args.name }); from a rest client i get the expected result.
However, when I try to access to root or Get("/", _ => { return View["index.sshtml"]; });, I get a 500 server error saying -
Error details are currently disabled. To enable it, please set TraceConfiguration.DisplayErrorTraces to true. For example by overriding your Bootstrapper's Configure method and calling environment.Tracing(enabled: false, displayErrorTraces: true)
I tried following the instruction in the error message and enable error tracing by including the following code in CustomBootstrapper.cs
protected override void ApplicationStartup(Nancy.TinyIoc.TinyIoCContainer container, IPipelines pipelines)
{
var environment = GetEnvironment();
environment.Tracing(true, true);
}
But then I get the following error when trying to run the application with dotnet run
Unhandled Exception: System.ArgumentException: An item with the same

I am not sure what's causing the error or how to enable tracing. Can anyone help?

The are two problems here :
IRootPathProvider and return Directory.GetCurrent().public override void Configure(INancyEnvironment environment) this adds the keys hence you the exception you are getting.
