Stuck with the Rest Operator lesson

Tell us what’s happening:
Hi all,

I am not able to pass through this lesson, please see my code below and the response I am getting.

Your code so far

const sum = (() => {
  "use strict";
  return function sum(...nums) {
    const args = nums;
    return args.reduce((a, b) => a + b, 0);
console.log(sum(1, 2, 3)); // 6

and the results are fine but I am getting this error and I am not able to understand it

The sum function uses the ... spread operator on the args parameter.

Link to the challenge:

you are asked to use the rest operator on the args argument, you are using it on a parameter named nums
