vault-helm: Consul Client Not Running on HA Mode of Vault

Vault should have consul client running, But, consul is not running,

kubectl exec vault-helm-0 -it sh
/ $ ps -ef | grep consul
28322 vault     0:00 grep consul

I have deployed Vault on k8s in HA and want to use consul as storage. The pods are not running.

vault-helm-0                           0/1     Running   0          162m
vault-helm-1                           0/1     Running   0          162m
vault-helm-2                           0/1     Running   0          162m.```

Also, I am receiving error even while passing the setting the variable env why?
