Cannot connect to any ethereum networks using API key

Question

I followed a tutorial about how to connect web3 with ethereum networks. I registered in infura.io and get all the urls. But when I try to connect to any network it is not connecting.When I print web3 connection status is always false. Below is my code and I use 1.0.0-beta.34 of web3

web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/v3/MY_API_KEY'));
web3.eth.net.getNetworkType(function(err, res){
     console.log("Network Type: "+res); //Displaying undefined
});

I tried with main net, ropsten and kovan. All are displaying undefined. I don't know what is the problem here. All example in web are showing these lines only. Can some one help me to solve this? Thank you.

You should add the web3-net into your dependencies libs also and then it will work properly

  "dependencies": {
    "web3": "1.0.0-beta.35",
    "web3-net": "1.0.0-beta.36"
  }

I run on my local and printout correctly as below

Network Type: rinkeby

sample source code: https://github.com/hadv/web3-client

const Web3 = require("web3")

web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/5rhaTHgnqnbTEFj1S1Ya'));
web3.eth.net.getNetworkType(function(err, res){
      console.log("Network Type: "+res);
});
