Hey @lucy7099! That means the docker container you're using in CI doesn't have the right dependencies installed in order to launch a browser. You'll want to change the container image to something that has the ability to launch a browser. For example, CircleCI provides images that can launch browsers with -browsers in their name (i.e. 14.17.6-browsers): https://circleci.com/developer/images/image/cimg/node

Tried using cimg/node:16.8.0-browsers however I have yarn install issues now. This was not the case before.
It says:

Make sure your network and proxy settings are correct.

My gitlabci configuration

percy:
  image: cimg/node:16.8.0-browsers
  variables:
    PERCY_TOKEN: "$PERCY_TOKEN"
  stage: percy
  script:
    - yarn install
    ...

manually installing these libraries for chromium in my gitlab set up worked for now
- apt-get install -y libnss3-tools libatk-bridge2.0-0 libdrm2 libxkbcommon0 libgbm-dev libasound2 libxshmfence-dev
