The tool will work efficiently the first time it runs the script. But when running the script after a reasonable time, you will encounter some lengthy track tracebacks, which are discouraging.
Unstable scripts are indeed authentic since most websites are constantly developing. So, when the site changes, the scraper will not be able to navigate and successfully scrap data.
