Angular 2 HTTP get handling 404 error

Solution 1
You need to pass a second callback to the subscribe method. This callback will execute when there is an error.
function handleError(error) {
console.log(error)
}
fetchData(){
return this.http.get('https://jsonplaceholder.typicode.com/psts/6')
.map(
(res) => res.json()
)
.subscribe(
(data) => console.log(data),
(error) => handleError(error)
);
}
Solution 2
There is no problem in your code, the URL itself is giving a 404
