The code doesn`t work at all for me

It return errors.. not only the code I wrote and reviewed several times, but also the code that comes ready in example1.html and example2.html It basically says that the .innerHTML property is null It doesn`t run in local files or workspace

Code:

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <link href='//fonts.googleapis.com/css?family=Varela+Round' rel='stylesheet' type='text/css'> <link rel="stylesheet" href="css/main.css"> <title>AJAX with JavaScript</title> <script> var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(){ if(xhr.readyState === 4){ document.getElementById("ajax").innerHTML = xhr.responseText; } }; xhr.open('GET','sidebar.html'); xhr.send(); </script> </head> <body> <div class="grid-container centered"> <div class="grid-100"> <div class="contained"> <div class="grid-100"> <div class="heading"> <h1>Bring on the AJAX</h1> </div> <div id="ajax">

      </div>
    </div>
  </div>
</div>

</div> </body> </html>
