Error: Failed to lookup view "home" in views directory

Why the app can't see the view called home? The same folder that contains app.js file contains a folder called "views" with file home.ejs. Here is the app.js file:

// jshint esversion:6
const express = require(`express`);
const ejs = require(`ejs`);
const app = express();

app.set(`view engine`, `ejs`);

app.use(express.static(`public`));

app.get(`/`, function(req, res) {
  res.render(`home`);
});

app.get(`/login`, function(req, res) {
  res.render(`login`);
});

app.get(`/register`, function(req, res) {
  res.render(`register`);
});

let port = process.env.PORT;
if(port == null || port == ``) {
  port = 3000;
}

app.listen(port, function() {
  console.log(`The server is now on.`);
});
