Kubernets prisma server not reachable - kubernetes

Question

I'm setting up a Kubernetes which is compose by prismagraphql and Postgres locally.
The Postgres container is setted up correctly and by using a NodePort I can access it from pgadmin locally.
Instead the prisma container is not reachable. I followed these steps (Guide) but I'm not able to find it at localhost:4466 also after the forwarding process.
This is the postgres.yaml:
# postgres config
apiVersion: v1
kind: ConfigMap
metadata:
name: postgres-config
labels:
app: postgres
data:
POSTGRES_DB: database
POSTGRES_USER: username
POSTGRES_PASSWORD: password

This is what I obtained with kubectl describe svc prisma-service:
