Elasticsearch Datasource not working

I have Grafana working with Prometheus as default datasource. Want to add Elasticsearch as a secondary data source. My environment is running in kubernetes with Elasticsearch : 7.2.0 , Grafana : 6.4.4

But getting error No date field named undefined found

I am able to curl ‘http://elasticsearch:9200/_cat/indices?v&pretty’ from Grafana pod
