M220 can connect with mongoshell but not with app

MongoDB University M220JS: MongoDB for Javascript Developers
#1

Hello,
I’m trying to set up the app for the M220 course for js developer.

I’ve followed the readme instructions and i can connect to the DB through the MongoShell correctly. On the MongoShell I see the collections and the items.

But I cannot connect true the app, if I run npm start, the movie list section is empty (the icon keeps spinning).

If I run the npm test -t connection-pooling command I got this error
Connection Pooling › Connection pool size is 50

expect(received).toBe(expected) // Object.is equality

Expected: 50
Received: undefined

Difference:

  Comparing two different types of values. Expected number but received undefined.

   8 |   test("Connection pool size is 50", async () => {
   9 |     const response = await MoviesDAO.getConfiguration()
> 10 |     expect(response.poolSize).toBe(50)
     |                               ^
  11 |   })
  12 | })
  13 |

Could someone pls help me?

I’ve made several errors in setupping the DB. PLS delete this topic :slight_smile:

#3

That is the expected behavior for the connection pooling test because we have not gotten to that point. The test is supposed to fail.

#4

What were the errors?

I’m having the same issues.

Thanks.
