Ingress-service error when deploying on gke

I’m deploying on gke and this is my ingress-service:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
    cert-manager.io/issuer: "letsencrypt-prod"
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
spec:
  # tls:
  #  - hosts:
  #    - humboi.com
  #    - www.humboi.com
  #    secretName: humboi-com
  rules:
  - 
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: main-server-ip-service
            port:
              number: 3000

But I get the following error in the ingress section of gke:

“Only ImplementationSpecific pathType supported”. So I change Prefix to ImplementationSpecific and that although shows a green check mark for the ingress and no error, the nginx load balancer is showing 404 for the app.
