Typeahead: Uncaught Error Missing source

I am getting this error in console everytime I try to run the following code

$('#autcomplete_search').typeahead({ highlight: true }, {
  name: 'apple_game',
  remote: "/search/autocomplete?keyword=make"

If fetching remote, you need to specify the engine. Here is an example from the docs

var bestPictures = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
  prefetch: '../data/films/post_1960.json',
  remote: '../data/films/queries/%QUERY.json'


$('#remote .typeahead').typeahead(null, {
  name: 'best-pictures',
  displayKey: 'value',
  source: bestPictures.ttAdapter()

in this example, bestPictures is your engine
