Whta is wrong with my code?

The interpreter takes too long, and gets an error. It does not tell me if it is right or wrong. though I feel as if this code should work. can someone confirm to me or explain alittle? this is my second time going through this course and I feel as if I am still missing something?

index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Rainbow!</title>
  </head>
  <body>
    <ul id="rainbow">
      <li>This should be red</li>
      <li>This should be orange</li>
      <li>This should be yellow</li>
      <li>This should be green</li>
      <li>This should be blue</li>
      <li>This should be indigo</li>
      <li>This should be violet</li>
    </ul>
    <script src="js/app.js"></script>
  </body>
</html>
js/app.js 
let listItems = document.getElementsById('rainbow')[0].getElementsByTagName('li');
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

for(var i = 0; i < colors.length; i ++) {
  listItems[i].style.color = colors[i];    
}

I believe this is a current issue with challenges right now. Not something wrong with your code.
