Good day to all.
I can't understand why VK.init doesn't work.
And I'm not sure yet, but I had to do it right. At the beginning, I went to the "create an application" item. I chose the item "Standalone-application". Next, I set up the website address and base domain. I used github pages.
And then, in the end, I wrote the following code (as in the documentation):

<!DOCTYPE html>
<html>
<head>
  <title>Test VK API</title>
  <script src="https://vk.com/js/api/openapi.js?153" type="text/javascript"></script>
<script type="text/javascript">
  VK.init({
    apiId: 	MY_ID
  });
</script>
</head>
<body>

</body>
</html>

Where MY_IDis the id of my application.
I go to the github pages site of my repository and see an error.

openapi.js?153:434 Uncaught TypeError: Cannot read property 'insertBefore' of undefined
    at Object.VK.init (openapi.js?153:434)
    at (index):8

index 8 is the initialization.
VK.init:

root = document.getElementById(VK._rootId);
    if (!root) {
      root = document.createElement('div');
      root.id = VK._rootId;
      body = document.getElementsByTagName('body')[0];
      body.insertBefore(root, body.childNodes[0]);
    }

Basically, I don't understand what I'm doing wrong.
