Profile Lookup single test fail

Tell us what’s happening:
Hello guys, look like my solution is work fine, I test it few times in browser console, but I don’t understand why one test for solution validation fails. I try to reset challenge, but it doesn’t help.

Test that fails:
“Akira”, “address” should return “No such property”

But I try it manually an see that it works fine!

Your code so far

var contacts = [
        "firstName": "Akira",
        "lastName": "Laine",
        "number": "0543236543",
        "likes": ["Pizza", "Coding", "Brownie Points"]
        "firstName": "Harry",
        "lastName": "Potter",
        "number": "0994372684",
        "likes": ["Hogwarts", "Magic", "Hagrid"]
        "firstName": "Sherlock",
        "lastName": "Holmes",
        "number": "0487345643",
        "likes": ["Intriguing Cases", "Violin"]
        "firstName": "Kristian",
        "lastName": "Vos",
        "number": "unknown",
        "likes": ["Javascript", "Gaming", "Foxes"]

function lookUpProfile(firstName, prop){
// Only change code below this line
  for (var i = 0 ; i < contacts.length; i++ ) {
    if (contacts[i].firstName === firstName && contacts[i].hasOwnProperty(prop)) {
      return contacts[i][prop];

  return "No such contact";
// Only change code above this line

// Change these values to test your function
lookUpProfile("Akira", "address");

The challenge instructions state:

If prop does not correspond to any valid properties then return “No such property”

I do not see where you are trying to return “No such property” when the prop specified does not exist in the a specific object.
