Elasticsearch-js: Memory leaks in .get() and .mget()

[PatrickHeneise]

"elasticsearch": "^11.0.1"

There seems to be a leak with lodash arrays, filling up memory and causing processes/containers to crash with simple .get() and .mget() operations.

'use strict'

const elasticsearch = require('elasticsearch')

let client = new elasticsearch.Client()
let i = 0

let mget = [{
  _id: 'one',
  _type: 'test',
  _index: 'test-dev',
  _source: true
}, {
  _id: 'two,
  _type: 'test',
  _index: 'test-dev',
  _source: true
}, {
  _id: 'three',
  _type: 'test',
  _index: 'test-dev',
  _source: true
}, {
  _id: 'four',
  _type: 'test',
  _index: 'test-dev',
  _source: true
}]

setInterval(() => {
  client.mget({
    body: {
      docs: mget
    }
  }, (e, r) => {
    console.log('interval:', i++, require('util').inspect(process.memoryUsage()))
  })
}, 50)

This should be fixed in v13
