How to have direct forwards be based off condition

[pkycho92]

i have yarp implemented using the direct forward pattern. in the endpoints.Map block i am checking for a condition. if the condition is not met, i would like to invoke the underlying controller that maps to the route instead of forwarding the request. is there any way to do this? as of now, if nothing occurs in the endpoints.Map block, it just returns a blank 200

    app.UseEndpoints(endpoints =>
    {
        endpoints.Map("path/{**catch-all}", async httpContext =>
        {
            if (conditionIsMet)
            {
                var error = await forwarder.SendAsync(httpContext, endpoint), httpClient, requestOptions, transformer);

                // Check if the proxy operation was successful
                if (error != ForwarderError.None)
                {
                    var errorFeature = httpContext.Features.Get<IForwarderErrorFeature>();
                    var exception = errorFeature.Exception;
                }
            }
            else
            {
                //how do i have the default controller that is mapped to this endpoint handle the request?
            }
        });
    });

Move the forwarder to a middleware:

    app.Use((context, next) =>
    {
            if (conditionIsMet)
            {
                var error = await forwarder.SendAsync(httpContext, endpoint), httpClient, requestOptions, transformer);

                // Check if the proxy operation was successful
                if (error != ForwarderError.None)
                {
                    var errorFeature = httpContext.Features.Get<IForwarderErrorFeature>();
                    var exception = errorFeature.Exception;
                }
            }
            else
            {
                await next(context);
            }
    });
    app.UseEndpoints(...)
