I tried emulate-device.js by setting url to http://pieroxy.net/blog/2014/11/18/user_agent_detection_in_java.html.
I got this error :

(node:2076) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 62)
I try to catch it, like this
try {
await crawler.queue('http://pieroxy.net/blog/2014/11/18/user_agent_detection_in_java.html');
await crawler.onIdle();
await crawler.close();
} catch (e) { }
Or this
(async () => {
.....
})().catch(() => { });
but without sucking. There's always that mistake.
