Micronaut 2.0.0 - Unable to invoke one service from another on kubernetes

Question

I have a service called Identity from which I want to invoke another service called Notification. Both services are built with Java 11, Micronaut 2.0.0 and are to be deployed on kubernetes.

The Notification service's kubernetes manifest look like this-

apiVersion: apps/v1
kind: Deployment
metadata:
  name: notification-service
  labels:
    app: notification-service
spec:
  selector:
    matchLabels:
      app: notification-service
  template:
    metadata:
      labels:
        app: notification-service
    spec:
      containers:
        - name: notification-service
          image: notification-service
          ports:
            - containerPort: 8080
          readinessProbe:
            httpGet:
              path: /health
              port: 8080
            initialDelaySeconds: 5
            timeoutSeconds: 3
          livenessProbe:
            httpGet:
              path: /health
              port: 8080
            initialDelaySeconds: 5
            timeoutSeconds: 3
            failureThreshold: 10
---
apiVersion: v1
kind: Service
metadata:
  name: notification-service
spec:
  type: NodePort
  selector:
    app: notification-service
  ports:
  - port: 8080
    protocol: TCP

To invoke this service, I have added a declarative client in Identity service as follows-

@Client(id="notification-service")
public interface NotificationClient {

    @Get("/health")
    String checkHealth();
}

Whenever I invoke the checkHealth() method after injecting it in any service or controller, the request gets stuck. The invocation works fine if I make the call from any service with Micronaut version 1.3.x.

Can anyone help with this?
