Declare a Read-Only Variable with the const Keyword -- bug

In this challenge, the last test is not passing. It is showing ( unexpected token ? ). i am totally stuck here. I heard that it’s a bug and someone already reported it couple of weeks ago. Then why isn’t it fixed yet ? What should i do ? someone please help to get through it.

function printManyTimes(str) {
  "use strict";

  // change code below this line

  const SENTENCE = str + " is cool!";
  for(let i = 0; i < str.length; i+=2) {

  // change code above this line

Yeah i know it’s a bug. But its not fixed yet and the first report was couple of weeks ago. So i made this post. Thanks

skip the challenge for now. Last time I saw it, it was fixed in github but I’m not sure how often the fixes make it back to the production environment.
