Not accepting solution although it works

Tell us what’s happening:
Describe your issue in detail here.
Hi, my solution is being rejected but I used console.log to confirm the solution. The error says:
" // running tests
findElement([1, 3, 5, 9], function(num) { return num % 2 === 0; }) should return undefined .
// tests completed"

So I used the function data from that error in a console.log to run through my code and it returns ‘undefined’ like expected. Not sure why it won’t accept it.

  **Your code so far**

function findElement(arr, func) {
for (let i=0; i<arr.length; i++){
  if(func(arr[i])) {
    return arr[i];
  }
} return "undefined";
}

console.log(findElement([1, 3, 5, 9], function(num) { return num % 2 === 0; }));
