Docs - product feedback: K6 script not getting the global __ENV from load_performance job

Summary

Unable to retrieve the value of ENVIRONMENT_URL in the K6 script

Steps to reproduce

Set up the following stages using the Load Performance Testing template,

stages:
  - deploy
  - performance

include:
  template: Verify/Load-Performance-Testing.gitlab-ci.yml

review:
  stage: deploy
  environment:
    name: review/$CI_COMMIT_REF_NAME
    url: http://$CI_ENVIRONMENT_SLUG.example.com
  script:
    - run_deploy_script
    - echo "ENVIRONMENT_URL=$CI_ENVIRONMENT_URL" >> review.env
  artifacts:
    reports:
      dotenv:
        review.env
  
load_performance:
  dependencies:
    - review
  variables:
      K6_TEST_FILE: ./load-test.js

Retrieve it in the K6 script, with the global __ENV variable,

export default function () {
  let res = http.get(`${__ENV.ENVIRONMENT_URL}`);

What is the current bug behavior?

Getting the following error:

time="2020-08-11T06:53:22Z" level=warning msg="Request Failed" error="Get https://undefined: lookup undefined on 10.30.0.2:53: no such host"
time="2020-08-11T06:53:22Z" level=error msg="GoError: invalid response type\n\tat native\n\tat file:///k6/load-test.js:42:28(17)\n"

What is the expected correct behavior?

The http.get(${__ENV.ENVIRONMENT_URL}) should return the value of the variable set in the deploy job and passed in the artifact $CI_ENVIRONMENT_URL
