I am using the JS client to connect to AWS Elasticsearch Service. With the setup:

```auto
import { Client, ClientOptions } from "@elastic/elasticsearch"

const {
  ES_AWS_ENDPOINT,
  ES_AWS_USER,
  ES_AWS_PASSWORD,
} = process.env

const options: ClientOptions = {
  node: ES_AWS_ENDPOINT,
  auth: {
    username: ES_AWS_USER,
    password: ES_AWS_PASSWORD,
  },
}

const client = new Client(options)

export default client

```

Which successfully connects from my local machine in development. When I run a build of the application with the same configuration, all requests from the application get the config error, saying I have no nodes declared. Is this method of connecting to Elasticsearch Service even supported? Why would it work locally and not from a build on an EC2 instance?

We don't support this service here so it might be hard to get information on that.

BTW did you look at [Cloud by Elastic](https://www.elastic.co/cloud), also available if needed from [AWS Marketplace](https://aws.amazon.com/marketplace/pp/B01N6YCISK) ?

Cloud by elastic is one way to have access to **all features** , all managed by us. Think about what is there yet like Security, Monitoring, Reporting, SQL, Canvas, Maps UI, Alerting and built-in solutions named [Observability](https://www.elastic.co/observability), [Security](https://www.elastic.co/security), [Enterprise Search](https://www.elastic.co/enterprise-search) and what is coming next 🙂 ...
