Help With Error "Something Went Wrong. Please Try Again Later"

[Chrisj]

I’m using this video web script where videos can be purchased to view.
Upon testing the purchasing process I see: “‘Something went wrong. Please try again later!!’,”

Any help or guidance on what to check or look at, or if you need me to provide more code to view, to resolve this issue in order to proceed with purchase test, will be appreciated:

function PT_MultipleBuyVideo() {
    var checked = getSelectedVideos();
    if (!checked) { return false; }

    swal({
        title: "",
        type: "info",
        html:"Simply proceed to purchase " + countSelectedVideos() + " videos(s) at a total cost of " + countTotalCredits() +" credits",
        showCancelButton: true,
        cancelButtonText: "Close",
        customClass: 'sweetalert-lg',
        confirmButtonText:'Proceed'
    }).then(function(){

        $.ajax({
            url: PT_Ajax_Requests_File() + 'aj/buy-video',
            type: 'POST',
            dataType: 'json',
            data: {id:checked},
        }).done(function(data){
            if (data.status == 200) {
                for (var i = 0; i < checked.length; i++) {
                    var button = $("button[data-action='multiple_select_button'][data-id='" + checked[i] + "']")
                    buttonMultipleSelectingStyle(button, 'purchased');
                }

                swal({
                    title: "Success",
                    type: "success",
                    html:"",
                    showCancelButton: true,
                    cancelButtonText: "Close",
                    customClass: 'sweetalert-lg',
                    confirmButtonText:'Go To Video(s)'
                }).then(function(){
                    window.location.href='/paid-list';
                });

            } else {
                if (data.error_num == 1) {
                    return swal(
                        'Error!',
                        'Not enough money',
                        'error'
                    );
                  }
           }
        }).fail(function() {
             swal(
                'Error!',
                'Something went wrong. Please try again later!!',
                'error'
            );
        })
    });
}

function buttonMultipleBuy(command) {
    var button = $("button[data-action='multuple-buy-video']");
    if (command == 'hide') {
        button.hide();
    } else if (command == 'show') {
        button.show();
    }
}

any help with resolving the error, to move to "Success" message, is appreciated
