AngularUI-Bootstrap's Typeahead Can't Read `length` Property of `undefined`

Question

I am getting the following error when I attempt to get a typeahead values from AngularUI-Bootstrap, using a promise.

TypeError: Cannot read property \'length         


        

Answer 1

$scope.getTypeaheadValues = function($viewValue)
{
    var someOutput="";//return something

    $http({
        method: 'GET',
        url: 'api/v1/person?name__icontains=' + $viewValue
    }).error(function (data) {
        console.error(data);
    }).success(function (data) {
        console.log(data);//Do whatever you want 
    });
return someOutput;

}

//The return statement is missing
