Helm nginx-ingress 404 error on all routes on GKE - kubernetes

Question

I am trying to deploy an app to GKE. I am using nginx-ingress controller and I have a bunch of ingress rules for every route. For some reason which am not sure, I am getting a 404 error on all the routes/pages.
One of the ingress resource definitions is:-
{{- $fullName := include "nginx.fullname" . -}}
{{- $ingressPath := .Values.ingress.path -}}
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: {{ $fullName }}-base
labels:
app: oxtrust
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/app-root: "/identity"
nginx.ingress.kubernetes.io/affinity: "cookie"
nginx.ingress.kubernetes.io/session-cookie-name: "route"
nginx.ingress.kubernetes.io/session-cookie-hash: "sha1"
spec:
{{- if .Values.ingress.tls }}
tls:
{{- range .Values.ingress.tls }}
- hosts:
{{- range .hosts }}
- {{ . | quote }}
{{- end }}
secretName: {{ .secretName }}
{{- end }}
{{- end }}
rules:
{{- range .Values.ingress.hosts }}
- host: {{ . | quote }}
http:
paths:
- path: {{ $ingressPath }}
backend:
serviceName: oxtrust
servicePort: 8080
{{- end }}
On minikube the setup is working okay since I do need to use nginx-ingress.
I really don't understand what I am doing wrong. I read somewhere about mandatory and cloud-generic objects should be deployed but I am not sure about that.
Someone shed some light on this please. Thank you
