Coverage report not showing anything in pipeline run

GitLab CI/CD
8

I am trying to figure out why this is not working Code coverage | GitLab

this is my yaml

# .gitlab-ci.yml

image: node:12

# Define the stages of the pipeline
stages:
  - test

cache:
  paths:
    - node_modules/

# Define the job that will run tests
test:
  stage: test
  script:
    - npm install
    - npm run test -- --coverage --verbose
  artifacts:
    when: always
    paths:
      - junit.xml
      - coverage/cobertura-coverage.xml
    reports:
      coverage_report:
        coverage_format: cobertura
        path: coverage/cobertura-coverage.xml
      junit: junit.xml
  # Add coverage to code coverage statistics
  coverage: '/All files[^|]*\|[^|]*\s+([\d\.]+)/'

  # Define when this job should be executed
  rules:
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event" && $CI_MERGE_REQUEST_TARGET_BRANCH_NAME == "master"'
