Select2 TypeError: b is undefined

Question

I'm using select2 to show ajax results in a dropdown but when I append data to select2 its showing error

TypeError: b is undefined

JS Code

        var baseurl = $("#baseurl").val();
        $(".myselect").select2({
            placeholder: "Select a inspector",
            allowClear: true,
            ajax: {
                url: baseurl + '/admin/getdata',
                dataType: 'json',
                type: "GET",
                quietMillis: 50,
                data: function (term) {
                    return {
                        term: term.term
                    };
                },
                results: function (data) {
                    var myResults = [];
                    $.each(data, function (index, item) {
                        myResults.push({
                            'id': item.id,
                            'text': item.firstname
                        });
                    });
                    return {
                        results: myResults
                    };
                }
            }
        });

term.term contains the value of input text in dropdown search box.

HTML

  <select class="myselect" style="width: 50% !important">
        <option></option>
        <option value="AL">Alabama</option>
        <option value="WY">Wyoming</option>
        <option value="KY">Kentucky</option>
  </select>

PHP SERVERSIDE CODE (LARAVEL)

 $searchtext = $request->get('term');
 $data = Inspector::latest('id')
                ->select('id', 'firstname', 'status', 'state', 'phone')
                ->where('firstname', 'LIKE', '%' . $searchtext . '%')
                ->get()->toArray();
 echo json_encode($data);

Any help is appreciated.

In your ajax configuration you use results you should use processResults

Try this

var baseurl = $("#baseurl").val();
    $(".myselect").select2({
        placeholder: "Select a inspector",
        allowClear: true,
        ajax: {
            url: baseurl + '/admin/getdata',
            dataType: 'json',
            type: "GET",
            quietMillis: 50,
            data: function (term) {
                return {
                    term: term.term
                };
            },
            processResults: function (data) {
                var myResults = [];
                $.each(data, function (index, item) {
                    myResults.push({
                        'id': item.id,
                        'text': item.firstname
                    });
                });
                return {
                    results: myResults
                };
            }
        }
    });
