Nodejs (typescript) communication error with elastic

Elastic Stack Elasticsearch
,
1

I have a problem connecting nodejs with elasticsearch, at this moment I have dockerized the version of Elasticsearch 8.6.0 as the documentation comes, the communication between kibana and elastic is correct since I have access and I have created indexes from kibana without any problem, now I have the error when connecting to nodeJs with typescript

import { Client } from '@elastic/elasticsearch'
const client = new Client({
    node: 'https://localhost:9200',
    auth: {
        username: 'elastic',
        password: 'elastic_pass'
    }
})

//Endpoint

  this.app.post('/testElastic', (req, res) => {
            client.index({
                index: 'index-test',
                document: {
                    character: 'Ned Stark',
                    quote: 'Winter is coming.'
                  }
            },)
        })

pd: I check using the netstat command that the nodejs container is at ::3000 (it does not specify address) and the elasticsearch container is 0 0.0.0.0:9200, Could it be the cause of my problem?
