Passes self-check asserts but not auto-tests

Hello, My solution passes the self-test asserts as well as the unit tests that I wrote myself. But for some reason I get a "NoExecFunction" error on the 1st auto-tests.

Below is my code (also attached the .js files). Can someone tell me what I'm missing"

function frequencySort(items) { let frequency = {} let newArr = [] let arrSet = new Set() const strNums = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']

items.forEach((num) =>{ arrSet.add(num.toString(10)); });

items.forEach((item) => { frequency[item] = frequency[item] ? frequency[item] + 1 : 1; });

arrSet.forEach((num) => { for (let i = 0; i < frequency[num]; i++) { strNums.includes(num) ? newArr.push(parseInt(num)) : newArr.push(num); } });

if (items.length <= 1 || arrSet.size === items.length) { return items; } else { return newArr; } }
