The Elasticsearch npm package is going to be deprecated soon, use @elastic/elasticsearch and @acuris/aws-es-connection so you don't have to provide IAM Credentails to the function.

Here the code, I use:

'use strict';

const { Client } = require('@elastic/elasticsearch');
const { createAWSConnection, awsGetCredentials } = require('@acuris/aws-es- 
connection');

module.exports.get_es_interests = async event => {
const awsCredentials = await awsGetCredentials();
const AWSConnection = createAWSConnection(awsCredentials);
const client = new Client({
...AWSConnection,
node: 'your-endpoint',
});

let bodyObj = {};
try {
    bodyObj = JSON.parse(event.body);
} catch (jsonError) {
    console.log('There was an error parsing the JSON Object', jsonError);
    return {
        statusCode: 400
    };
}

let keyword = bodyObj.keyword;

const { body } = await client.search({
index: 'index-name',
body: {
  query: {
    match: {
      name: {
        query: keyword,
        analyzer: "standard"
      }
    }
  }
}
});

var result = body.hits.hits;

return result;
};
