I am testing the deployment of wso2is-5.12.0-beta3 in a Kubernetes cluster and I have added the below mentioned hazelcast configuration to the deployment.toml according to the documentation.

https://is.docs.wso2.com/en/5.11.0/setup/deployment-guide/#!

I’m getting the below exception once the server starts up.

A direction to resolve this issue is highly appreciated.
Thanks in advance.

local_member_host = "$env{LOCAL_MEMBER_HOST}"
