7 months ago Hi @Allamaris0, sorry you're running into issues. Are you running your cloud on the same machine? Or is it remote? If remote, you need to provide the ip/port of your server. ShowChrome will only work on the machine where Cloud (and thus Chrome) are installed, and needs to have a GUI. If it's linux, for instance, it won't work without xvfb. If none of these are your issues, you mentioned "showChrome" doesn't work - does headless work?

Hello. I'm a beginner and I got error at start with an example code :(
`const Hero = require('@ulixee/hero');
// process.env.ULX_SHOW_CHROME = 'true';
(async () => { const url =
https://dataliberationfoundation.org/; console.log('Opened Browser'); const hero = new Hero({ showChromeInteractions: true, showChrome: true });await hero.goto(url, 5e3); await hero.waitForPaintingStable();
await hero.waitForMillis(5e3); await hero.close(); })();`
`Opened Browser
