UnhandledPromiseRejectionWarning

I try running a basic example on this repo and I'm getting UnhandledPromiseRejectionWarning. youtube-dl version: 3.0.2

This is my code:

const fs = require('fs')
const youtubedl = require('youtube-dl')

const url = 'https://www.youtube.com/watch?v=LXb3EKWsInQ'
const options = ['--format=18']
const outputFile = 'wildlife-4k.mp4'

const video = youtubedl(url, options, { cwd: __dirname })
video.on('info', function(info) {
  console.log('Download started')
  console.log('filename: ' + info._filename)
  console.log('size: ' + info.size)
})

video.pipe(fs.createWriteStream(outputFile))

and this is the error:
