Frontend app works ok with Port forwarded localhost endpoint but fails with an ingress endpoint

I am able to access the chatbot front end using port forwarded local host ep.
Now I want to expose this endpoint using Ingress. I have added an ingress to expose the chatbot’s front end using the below manifest
e125830@W76CYQCV44 nim-operator % cat cr8-rag-chatbot-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: rag-chatbot-ep
namespace: rag-sample
spec:
ingressClassName: nginx
rules:

• host: rag-chatbot-ep.k8s-performance.stage.stl.k8s.int
  http:
  paths:
  • backend:
    service:
    name: rag-playground-multiturn-rag
    port:
    number: 3001
    path: /
    pathType: Prefix
    tls:
• hosts:
  • rag-chatbot-ep.k8s-performance.stage.stl.k8s.int

I am able to get to the chatbot front end using the new ingress ep https://rag-chatbot-ep.k8s-performance.stage.stl.k8s.int/converse, but when I submit a prompt I get error
Below are the logs and my analysis…

Below are the logs when Chatbot is accessed via nginx ingress ep

Main issue is the POST call is missing /content/converse in the ingress ep case

Looks like the the URL posted by the Client itself does not have them for ingress case…

Can one of you please check this and let us know what might be causing this difference in the POST URL’s when using the above endpoints…

Commencez par cr8-rag-chatbot-ingress.yaml et comparez les chemins des requêtes ingress avec les logs obtenus via le port forwarding. Suivez la manière dont le frontend construit l’URL POST pour /queue/join et vérifiez que le endpoint ingress conserve le préfixe /content/converse ; c’est terminé lorsque la soumission d’un prompt via ingress réussit comme via le port forwarding.
