PHP seems to be resistant to receiving data from ajax requests

I am attempting to develop a drag and drop file upload feature without using a traditional form, utilizing JavaScript's FormData. However, I am encountering an issue where PHP does not seem to be receiving the uploaded file. Could there be some missing request headers or another factor that I am overlooking?

JavaScript:

if (item.kind === 'file') 
            {
                const file = item.getAsFile();
                const fileFormData = new FormData();
                fileFormData.append('file', file);
                $.ajax({
                    url: "backend/uploadFiles.php",
                    type: 'POST',
                    data: fileFormData,
                    cache: false,
                    contentType: false,
                    processData: false,
                    success: function (returndata) {
                        console.log(returndata);
                    }
                });

PHP:

<?php
var_dump($_POST);
var_dump($_GET);

PHP output:

array(0) {
}
array(0) {

}

To access uploaded files, they are stored in the $_FILES array which is a collection of items sent to the current script through the HTTP POST method. For more information, visit https://www.php.net/manual/en/reserved.variables.files.php

var_dump($_FILES)

Ensure that file_uploads is enabled in the php.ini configuration file.
