Api-gateway and service routers

HI have been playing around with the learn-consul-canary repo from hashicorp education. I extended this and created a service router for the frontend. The service router uses query parameter to decide to route to V1 or V2 front end. This all works fine and i can seamlessly hit either version of my choosing using this. The flow in the hashicups is,

api-gateway → nginx - > front-end

ubuntu@cdoyle-consul:~/learn-consul-canary-deployments$ curl -s http://localhost:32321/?version=v1 | sed -n 's/.*\(HashiCups-v[0-9]\+\).*/\1/p'; echo
HashiCups-v1
ubuntu@cdoyle-consul:~/learn-consul-canary-deployments$ curl -s http://localhost:32321/?version=v2 | sed -n 's/.*\(HashiCups-v[0-9]\+\).*/\1/p'; echo
HashiCups-v2

I then wanted to try removing nginx for the routing and instead just use API gateway to route to the frontend service. However when i do this the gateway doesnt setup the route when there is a service router applied on the service, if i remove the service router then gateway will start routing.

Is there a way to define a route in api-gateway that will use the service router logic to decide which service instance to route too?

config files are
