[DIRECTcut]

Expected Behavior

When an unavailable video is requested, the server catches an Error and sends it to the client as JSON.

Current Behavior

When an unavailable video is requested, the server emits an Error. The app hangs without exceptions.

Possible Solution

Catch errors on ytdl.getInfo() (/api/info route) and send them to the client;

Steps to Reproduce

1. Open the app
2. Paste an unavailable video's link (https://www.youtube.com/watch?v=U_RAWwgCwS1)
3. Press 'Submit'

}

Was able to catch errors on '/api/info' endpoint. Attempts to do the same on '/api/download' did not succeed, get the following error (server-side):
