Error in passing the password in servers.json file while deploying pgadmin4 in kubernetes cluster

deployment.yaml file

containers:
- image: postgres:8.4
env:
- name: PFADMIN_SERVER_JSON_FILE
value: /pgadmin4/servers.json
volumeMounts:
- name: server-config
mountPath: /pgadmin4/servers.json

subPath: pgpass
volumes:

configmap for servers.json
kind: ConfigMap
apiVersion: v1

data:
servers.json: |

}
}
}

configmap for pgpass
kind: ConfigMap

data:
pgpass: |
hostname:port:database:username:password

The issue is when i log in to the postgres, i can see the server but it is
prompting me to enter the password so it is not able to read the one i
supplied.

i get this error in the UI: connection failed: fe_sendauth: no password
supplied
