Create Strings using Template Literals - Not recognizing template string

Tell us what’s happening:
I’m sure that I’m using template literals, however the “Template strings were used” objective is not completing and I’m seeing ‘Invalid regular expression flags’ in the test area. What’s going wrong?

Your code so far


const result = {
  success: ["max-length", "no-amd", "prefer-arrow-functions"],
  failure: ["no-var", "var-on-top", "linebreak"],
  skipped: ["id-blacklist", "no-dup-keys"]
};
function makeList(arr) {
  "use strict";

  // change code below this line
  const resultDisplayArray = arr.map(value => `<li class="text-warning">${value}</li>` );
  // change code above this line

  return resultDisplayArray;
}
/**
 * makeList(result.failure) should return:
 * [ <li class="text-warning">no-var</li>,
 *   <li class="text-warning">var-on-top</li>, 
 *   <li class="text-warning">linebreak</li> ]
 **/
const resultDisplayArray = makeList(result.failure);
console.log(resultDisplayArray);

Nevermind - This is apparently a bug:
