URL Shortener Microservice 1st 2nd tests not passing

I’m not sure why the second test doesn’t pass when I can actually send the information to MongoDB Atlas. I also don’t know why I can’t seem to redirect for the third test.

app.post('/api/shorturl', async (req, res) => {
  const { url } = req.body;
  dns.lookup(url, (err) => {
    if (err) {
      res.json({ error: 'invalid url' });
  const urlObj = { original_url: url, short_url: getRandomInt(1, 10000) };
  const urlDoc = new shortURL(urlObj);
  await urlDoc.save();

app.get('/api/shorturl/:short_url', async (req, res) => {
  const { short_url } = req.params;
  await shortURL.findOne({ short_url }, (err, doc) => {
    if (err) {
    } else {
      const { original_url } = doc;

I also get the following on glitch console

      throw er; // Unhandled 'error' event
TypeError: Cannot destructure property `original_url` of 'undefined' or 'null'.

Any help would be appreciated, thank you.

Hello there,

One thing to note: dns.lookup expects only the hostname as the first argument.
