MongoDB error on connection 'MongoServerSelectionError',

Question

   const uri = 'mongodb+srv:<username>//:<passwod>@chatapp-qrps3.azure.mongodb.net/test?retryWrites=true&w=majority'

   const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true })

   client.connect(err => {
       console.log(err)
       client.close();
   });

error seems like this

MongooseError [MongooseServerSelectionError]: connection to 40.79.242.22:27017 closed at new MongooseServerSelectionError (/Users/sherin/Desktop/sherinshaju/reactsocket/node_modules/mongoose/lib/error/serverSelection.js:22:11) at NativeConnection.Connection.openUri (/Users/sherin/Desktop/sherinshaju/reactsocket/node_modules/mongoose/lib/connection.js:823:32) at Mongoose.connect (/Users/sherin/Desktop/sherinshaju/reactsocket/node_modules/mongoose/lib/index.js:333:15) at Object.

I think the form of the URI should be in the following manner:

const mongoURI = 'mongodb+srv://<username>:<password>[email protected]/test'

I think you have missed out the username in your URI.
