В чем может быть проблема?

#2 
desiredCapabilities: {
    browserName: process.env.BROWSER || 'chrome',
    chromeOptions: {
      args: [
            '--disable-gpu',
            '--headless',
            '--no-sandbox',
          ],
      prefs: {
        'download.default_directory': __dirname + '/tmp/test/download',
        'download.prompt_for_download': false
      }
    }
  },

Проблема решена этим, но…

Теперь другая проблема…

#4 
          docker exec idg sh -c "Xvfb -ac :99 -screen 0 1280x1024x16 +extension RANDR > /dev/null 2>&1 &"
          docker exec idg sh -c "sleep 3"
          docker exec idg sh -c "export DISPLAY=:99"

Сделано, но не помогает…

#5

думаю что DISPLAY надо объявлять в том же exec в котором вызывается selenium
