Swagger.ObjectModel.Builders.RequiredFieldException: 'Paths' is required

Question

Using Nancy v 1.4.1 and Nancy.Swagger v 2.1.1 (the last one that supports Nancy v1), I get the above error when navigating to the /api-docs path. Any ideas? No setup steps I've seen says anything about the 'Paths' field.

My Module:

public class General : NancyModule
{
    public General()
    {


        Get["/","Home"] = parameters =>
        {
            try
            {
                return "home";// View["view/index.html"];
            }
            catch (Exception ex)
            {
                return ExceptionHelper.ExceptionResponse(Negotiate, ex);
            }
        };

        Get["/test/", "Test"] = parameters => {
            return "testie";
        };
    }
}

My Module metadata:

public class GeneralMetadataModule : MetadataModule<PathItem>
{
    public GeneralMetadataModule(ISwaggerModelCatalog modelCatalog)
    {
        Describe["Test"] = description => description.AsSwagger(
            with => with.Operation(
                op => op.OperationId("Test")
                        .Tag("Users")
                        .Summary("The list of users")
                        .Description("This returns a list of users from our awesome app")));
    }
}

You have it in wrong order - name should be first, then path

Get["Home", "/"] = parameters =>  //this is right
{
    try
    {
        return "home";// View["view/index.html"];
    }
    catch (Exception ex)
    {
        return ExceptionHelper.ExceptionResponse(Negotiate, ex);
    }
};

Get["Test", "/test/"] = parameters => {  //and this is right
    return "testie";
};
