Looking deeper into the logs of my server and printing the http header user-agent i found the User Agent from Google Page Speed Insight are the below two instances

{   "pattern": "Chrome-Lighthouse",
    "instances": [
      "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3694.0 Safari/537.36 Chrome-Lighthouse",
      "Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3694.0 Mobile Safari/537.36 Chrome-Lighthouse"
    ]}

i'm using these object to validate with a regex if the user agent is a bot

regex = RegExp("Chrome-Lighthouse","ig")
regex.test("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3694.0 Safari/537.36 Chrome-Lighthouse")
