OpenSearch Security not initialized error in master node

Tested with the below and it works fine:

clusterName: "opensearch-cluster"
nodeGroup: "master"

# If discovery.type in the opensearch configuration is set to "single-node",
# this should be set to "true"
# If "true", replicas will be forced to 1
singleNode: false

# This should be set to clusterName + "-" + nodeGroup for your master group
masterService: "opensearch-cluster-master"

# OpenSearch roles that will be applied to this nodeGroup
# These will be set as environment variable "node.roles". E.g. node.roles=master,ingest,data,remote_cluster_client
