I create a externalName service to aws RDS db, everything works just fine except Dashboard status always pending. How to fix the dashboard status, is there any annotation to resolve it ?

• Kubernetes 1.14
• Istio 1.4.2
• Dashboard v2.0.0-beta4+0.gf232c589
• AWS EKS.7

apiVersion: v1
   kind: Service
   metadata:
     labels:
       app: postgres
     name: postgres
     namespace: staging
   spec:
     externalName: db-staging.xxxxxxxxxxx.ap-southeast-1.rds.amazonaws.com
     type: ExternalName
     ports:
       - port: 5432
   status:
     loadBalancer: {}

Dashboard always show pending for externalName service
