Actually when I sent the request from Postman I am able to get the status Okay-- 200. But getting the following error in the terminal. Can anyone please help.
Error :

Hi @Mrudula_Kulkarni,

I believe you should await the result, i.e:

const result  = await ...

It is an asynchronous operation so result won’t have a defined value. In the next step you’re ending the connection before inserting.

SO-Related.

Edit/Comment: const result seems unnecessary. const result = await db.collection... could just become await db.collection...

If you want to test that the value is still undefined for the resolution, use console.log(result)
