I want to get the html dom of grafana page using jsoup

I want to get html dom of grafana page using jsoup.
(A single page consists of several dashboards.)
But it wasn’t possible. The error was:

If you’re seeing this Grafana has failed to load its application files

  1. This could be caused by your reverse proxy settings.
  2. If you host grafana under subpath make sure your grafana.ini root_url setting includes subpath
  3. If you have a local dev build make sure you build frontend using: npm run dev, npm run watch, or npm run build
  4. Sometimes restarting grafana-server can help

Also, I found the same error when I made a GET request with postman.
I need to make a rendered Grafana page into a single image. Please help me. :frowning:

If it is impossible, please explain in detail why it is impossible.
I’m guessing it’s to prevent attacks via bots, but I can’t find the code to block those bots.
