The console does not show the same as in the video

This is my code in widget.js:

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
 if(xhr.readyState === 4) {
   console.log(xhr.responseText);
 }
};
xhr.open('GET', '../data/employees.json');
xhr.send();

and html fragment (in index.html), in the same place as in the video:

  <script scr="js/widget.js"></script>

The path given in JS for employees.json required adding "../" because otherwise the console showed a 404 error, and sometimes it did not show anything. After correcting the path, the console (google chrome) does not show JSON content, and I can only see something like this:

Where am I making a mistake? Why the console does not show JSON content?

You have a typo.

<script scr="js/widget.js"></script>

scr should be src.
