Basic JavaScript - Record Collection

Hey Guys, not sure where i’ve gone wrong here, any help much appreciated.

The error code is the following: TypeError: can’t assign to property “artist” on 5439: not an object

Your code so far

// Setup
const recordCollection = {
  2548: {
    albumTitle: 'Slippery When Wet',
    artist: 'Bon Jovi',
    tracks: ['Let It Rock', 'You Give Love a Bad Name']
  },
  2468: {
    albumTitle: '1999',
    artist: 'Prince',
    tracks: ['1999', 'Little Red Corvette']
  },
  1245: {
    artist: 'Robert Palmer',
    tracks: []
  },
  5439: {
    albumTitle: 'ABBA Gold'
  }
};

// Only change code below this line
function updateRecords(records, id, prop, value) {
 if (value == ""){delete id.prop}
  
  if (prop != "tracks" && value != ""){
    id.prop = value
  }

  if (prop == "tracks" && value != "" && id.hasOwnProperty("tracks") == false){id.push([value])

  } 

  if (prop == "tracks" && value != ""){
    (id.tracks).push(value)
  }
  
  return records;
}

updateRecords(recordCollection, 5439, 'artist', 'ABBA');
