WebSocket error when using Playwright on GitLab CI

I am using Playwright with Jest and jest-playwright-preset and trying to get my tests to run in GitLab CI.

My .gitlab-ci.yml:

ui_test:
  image: node:latest
  script:
    - npm install
    - npm run test:ui

When I run this locally on my Windows machine everything works fine. However if I try to run in GitLab CI I get the following error:

 2020-06-26T21:01:39.770Z pw:api => chromium.launchServer started
 2020-06-26T21:01:39.786Z pw:api <= chromium.launchServer succeeded

     Note: use DEBUG=pw:api environment variable and rerun to capture Playwright logs.

EDIT: This has nothing to do with Jest. The same problem will arise when only using Playwright and using the node image instead of the Playwright image.
