This machine is sending different environment parameters than the first machine that started this parallel run.

Hey there! I’m receiving this error just recently in my Github Actions that run multiple tests in parallel:

/opt/hostedtoolcache/node/14.20.1/x64/bin/npx cypress cache list

You passed the --parallel flag, but we do not parallelize tests across different environments.

This machine is sending different environment parameters than the first machine that started this parallel run.

The existing run is: https://dashboard.cypress.io/projects/<:)>/runs

In order to run in parallel mode each machine must send identical environment parameters such as:

 - specs
 - osName
 - osVersion
 - browserName
 - browserVersion (major)

This machine sent the following parameters:

{
  "osName": "linux",
  "osVersion": "Ubuntu - 20.04",
  "browserName": "Chrome",
  "browserVersion": "106.0.5249.91",
  "specs": [
    ...
  ]
}

Cypress module has returned the following error message:

Error: Could not find Cypress test run results

I can confirm that a view of the jobs are running Chrome 105 and other Chrome 106. Here is my workflow configuration:

jobs:
  transact:
    name: Transact
    runs-on: ubuntu-latest
    strategy:
      # when one test fails, DO NOT cancel the other
      # containers, because this will kill Cypress processes
      # leaving the Dashboard hanging ...
      # https://github.com/cypress-io/github-action/issues/48
      fail-fast: false
      matrix:
        # Specifies the concurrency of tests to run
        container: [1, 2, 3, 4, 5]
    steps:
      - name: Run Cypress tests
        id: e2e-tests
        uses: cypress-io/github-action@v4
        with:
          browser: chrome
          record: true
          parallel: true
          group: 'Transact'
          config: baseUrl=${{ github.event.inputs.baseUrl }}
          env: apiHost=${{ github.event.inputs.apiHost }}
        env:
          CYPRESS_RECORD_KEY: ${{ secrets.TRANSACT_CYPRESS_RECORD_KEY }}
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Is Github using different versions of chrome on their ubuntu-latest image? 🤔

Have got this working with setup-chrome after finding this comment https://github.com/cypress-io/github-action/issues/518#issuecomment-1210979047

As we use a custom command, had to specify --browser ${{ env. BROWSER_PATH }} in that command

Any updates on this? It happens for us almost monthly and seems to be whenever chrome updates! I agree that the check against browser matching for environments could be configured to solve for this issue and be less strict
