Nginx Ingress controller with K8s returning 404

Question

I have a service which is accepting the request at /api/v1/orders. I was able to validate the response using the Cluster IP. I logged into a pod and hit the curl http://order-service/api/v1/orders and getting the response.

I then set up a Nginx Ingress Controller and the ingress with the below yaml definition. I used the cafe example and the cafe ingress is working fine.

When I try to access my order-service I am getting 404. I am not sure how to debug this.

Note: My API is accessible on http://context/api/v1/orders endpoint. How do I redirect the path the /orders/api/v1/orders from the ingress?

curl -v -H "Content-type: application/j son" -H "Accept: application/json" https://classpath.com/orders/api/v1/orders --insec ure

I have set the aws loadbalancer IP to classpath.com in the /etc/hosts file.
