How to fix 'abort' error from Select2 plugin?

I'm working with v4.0.13 of Select2 library and using AJAX as the data source. I keep encountering an 'abort' error in response.statusText whenever I type at a faster speed in the dropdown's search field. Besides the error encounter, the plugin does work correctly.

I tried removing the delay option but that didn't help. A user on SO also mentioned this issue as part of another question, but I thought I'd create a new question for it specifically.

What is the reason for this issue, and how can I fix it? It appears to be a client-side issue. I am not getting errors on the server.

My code:

<script>
    $('.js-data-example-ajax').select2({
        ajax: {
            url: function (parameters) {
                return 'clients?handler=Clients&searchValue=' + parameters.term;
            },
            dataType: 'json',
            delay: 350,
            error: function (response) {
                console.error(response);
            }
        },
        minimumInputLength: 2,
        dropdownAutoWidth: true
    });
</script>

<select class="js-data-example-ajax"></select>
