warning Error from chokidar - Error: ENOSPC: System limit for number of file watchers reached

After running the dev server and before the Cypress run I get thousands of logs about exceeding file watchers.

Curious if this is something that can be rectified via the plugin interface somehow or if it's an issue with Github Actions? The test eventually runs fine, but in order to see the results you have to scroll through thousands of logs to find them.

I was able to fix this by including CHOKIDAR_USEPOLLING=1 in my start command.

Ultimately it looks like it's not an issue with this action but with Gatsby's dev server. Got the idea from this thread in Gatsby's repo: gatsbyjs/gatsby#15843

// package.json
"develop:ci": "CHOKIDAR_USEPOLLING=1 npm start"

// workflow yml
 - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          start: npm run develop:ci
          wait-on: http://localhost:4000
          wait-on-timeout: 6000
