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' }); bestPictures.initialize(); $('#remote .typeahead').typeahead(null, { name: 'best-pictures', displayKey: 'value', source: bestPictures.ttAdapter() }); in this example, bestPictures is your engine
