Runtime error during simple test #15

Hey there. I'm using this version:

k6 v0.47.0 (go1.20.13, linux/amd64)
Extensions:
  github.com/gjergjsheldija/xk6-mllp (devel), k6/x/mllp [js]

And running a simple test through docker with:

docker run --volume "$(pwd)/examples":/test --workdir "/test" -i k6local:latest run /test/test.js

I edited the test.js script according to my needs (mostly adding my server url):

import {Hl7} from 'k6/x/mllp';
import {sleep} from 'k6';

const config = {
    host: '192.168.0.59',
    port: '5107'
}

const client = new Hl7(config);

export const options = {
    vus: 2,
    duration: '1s',
};

 export default function () {
    client.send('/test/sample.hl7');
    sleep(0.5)
 }

My server receives one message correctly for each vu, but at the second iteration, this is the error I get:

          /\      |‾‾| /‾‾/   /‾‾/
     /\  /  \     |  |/  /   /  /
    /  \/    \    |     (   /   ‾‾\
   /          \   |  |\  \ |  (‾)  |
  / __________ \  |__| \__\ \_____/ .io

  execution: local
     script: /test/test.js
     output: -

  scenarios: (100.00%) 1 scenario, 2 max VUs, 31s max duration (incl. graceful stop):
           * default: 2 looping VUs for 1s (gracefulStop: 30s)

hi @pirods
can you try building with docker like :

 docker run --rm -it -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" grafana/xk6 build v0.43.1 \
--with github.com/gjergjsheldija/xk6-mllp=.

and then running as described in the docs ?
