Welcome there,

You have two of the same route:


myDB(async (client) => {
  const myDataBase = await client.db('database').collection('users');

  // Be sure to change the title
  app.route('/').get((req, res) => {

Otherwise, it could be an issue with your Database URI, if you are getting a cannot read property ‘split’ of null.

Hope this helps

Could you please tell me how should i define the route? cause even when i didnt write the first block of code the second block still gave me the error Cannot GET /

The answer is given at the end each lesson. If you are struggling with how to use Express, I recommend you go back to the challenges covering it:

Otherwise, it would help to see the full error message.

Hope this helps
