I'm learning ElasticSearch (hosted on AWS). I'm using the javascript sdk and this connectionClass.

My code:

let es = require('elasticsearch');
let client = new es.Client({
  hosts: [''],
  connectionClass: require('http-aws-es')
});

function handler() {
  let params = {
    index: 'product',
    q: 'bar'
  };
  client.search(params, (err, data) => {
    if (err) {
      console.log('Error ', err);
    } else {
      console.log('Data ', data);
    }
  })
}

handler();

Problem: When I run the code I get the following error:

Error: Request error, retrying
  POST https:// => The "data" argument must be one of type string, TypedArray, or DataView
at checkRespForFailure (/Users/oscarandersen/WebstormProjects/peego/lambda/indexElasticSearch/node_modules/elasticsearch/src/lib/transport.js:266:18)

      at startup (bootstrap_node.js:193:16)
      at bootstrap_node.js:617:3

I cant figure out what the problem is, any help is appreciated.

• javascript
• elasticsearch
• aws-elasticsearch

• From the error message, I think you should remove https:// from the hosts parameter. – Pierre-Nicolas Mougel Commented Jun 7, 2019 at 9:09

I am not sure how useful this answer will be to you 4 months later but I ran into the same problem and the solution was to set the region for the AWS sdk. There are a number of approaches to this, the one I used was pulling in the aws-sdk to my server.js file and adding AWS.config.update({ region: "us-west-2" });
