Bug in ES6: Create Strings using Template Literals with Err Msg: Invalid regular expression flags

Describe your problem and - if possible - how to reproduce it

The Challenge, ES6: Create Strings using Template Literals, return an error message Invalid regular expression flags.

My solution is,

arr.map(a=>`<li class="text-warning">${a}</li>`);

where the console log shows the correct solution,

["<li class="text-warning">no-var</li>", "<li class="text-warning">var-on-top</li>", "<li class="text-warning">linebreak</li>"]

And the full code is,

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(a=>`<li class="text-warning">${a}</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);

Still buggy… My solution, (though I tried the looping solution and some listed above) No luck

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

yeilds:

// running test
Invalid regular expression flags
// tests completed

I hate leaving assignments undone, does anyone have a workaround? 🐞

This works for me for today: 21-08-2018 No Bugs for: template strings were used const resultDisplayArray = arr.map(err => <li class="text-warning">${err}</li>);
