Configure sweetalert2 outputting raw json

I want to show sweetalert message if registration succeeds or fails (I wrote sweetalert code in jquery file) and included it in registration view page (it is included in master.blade.php which propagates to all pages) but displaying instead sweetness message or success message, it keeps displaying parsed json message.

These are the generated files.

custom_file.js

$(document).ready(function () {

    var form = $('#registration');

    form.submit(function (e) {
        e.preventDefault();

        $.ajax({
                url: form.attr('action'),
                type: "POST",
                data: form.serialize(),
                dataType: "json"
            })
            .done(function (response) {
                if (response.success) {
                    swal({
                        title: "Hi " + response.name,
                        text: response.success,
                        timer: 5000,
                        showConfirmButton: false,
                        type: "success"
                    });

                    window.location.replace(response.url);

                } else {
                    swal("Oops!", response.errors, 'error');
                }
            })
            .fail(function () {
                swal("Fail!", "Cannot register now!", 'error');
            });
    });
