Chrome parallel-group-params-mismatch error

We use parallelized actions with browser: chrome, it worked well until yesterday. Now sometimes (not always) we have this behavior :

A first container starts with apparently Chrome 98 :

The other containers start a minute later and show us this error :

It says the specs mismatch, I guess it is because of the Chrome version here being Chrome 99 ?

So only 1 container (the first starting) goes ✅ and the others fail like above ❌

The configuration of our Github Action is like this :

- name: Cypress run
              uses: cypress-io/github-action@v2
              with:
                  browser: chrome
                  build: npm run build
                  config-file: cypress/cypress-ci.json
                  group: "Chrome"
                  parallel: true
                  record: true
                  start: [our starting script]
                  wait-on: [our local url]

I don’t see a way of specifying a particular browser version with this action, am I missing something ?

I solved this problem by avoiding the browser bundled with GitHub Actions.

Basically, I install the latest version of chromium and just use that.

Here’s what that code looks like in our GitHub action.

If the Cypress team doesn’t want to update the action itself to handle this mismatch, it might make sense to provide some examples in the documentation for how to avoid this problem!

- uses: browser-actions/setup-chrome@latest
- run: |
    echo "BROWSER_PATH=$(which chrome)" >> $GITHUB_ENV

- name: Run Cypress tests 🚀
  uses: cypress-io/github-action@v4
  with:
    install: false
    record: true
    parallel: true
    browser: "${{ env.BROWSER_PATH }}"
    start: "your start command"
  env:
    CYPRESS_RECORD_KEY: ${{ secrets.recordKey }}
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }

For information the situation solved itself after a day or two but it is still happening sometimes, like today for a mismatch between Chrome 101 and Chrome 102
