Issue(solved): Still show stack trace when I apply try-catch

function getProfile(username) {
  const URL = `teamtreehouse.com/${username}.json`
  try {
    const request = https.get(URL, res => {
      let body = ''
      res.on('data', data => {
        // read the data from buffer type
        body += data.toString()
      })

      res.on('end', () => {
        // parse the data
        const profileObj = JSON.parse(body) 
        // print the data
        printMessage(username, profileObj.badges.length, profileObj.points.JavaScript)
      })
    })

    request.on('error', error => {
      console.error('Problems is', error.message);
    })
  } catch (error) {
    console.log('Problem is:', error)
  }
}

cmd below

I'm failing to understand your question? The try-catch is doing exactly what it's supposed to do, it's logging out an error that occurred within the try branch.

As for the error itself you'll have to look up information about the https.get function, because on of your parameters is either in the incorrect format, or you are providing it with a bad domain.
