I have a docker stack deployment inside which I have elastic search deployed as a service. Now I have another NodeJS application inside the same docker stack deployed as service. I am using the Official elastic search Client (@elastic/elasticsearch ) to make calls to Elastic from my node application. Now I am able to connect to elastic using Normal REST call like "[http://elasticsearch:9200](http://elasticsearch:9200)"
But the Client is not able to connect using this above URL.
const { Client } = require('@elastic/elasticsearch');
const client = new Client({ node: "[http://elasticsearch:9200](http://elasticsearch:9200)"});
Anyway to get this working?.
HEre is my elastic service defined in my stack yml file.
elasticsearch:
