submit form with no files

[kdbdevops]

I need to be able to submit the dropzone form with no files added. For some reason when the form is submitted without a file, dropzone does not handle the submit action and the http handler (ashx) treats the request like a full page submission. Am I missing a configuration option to handle this case?

    Dropzone.autoDiscover = true;
    Dropzone.options.myDropzone = {
        url: "hn_FileUpload.ashx",
        previewsContainer: "#previewFiles",
        autoProcessQueue: false,
        uploadMultiple: true,
        maxFilesize: 100, // MB
        parallelUploads: 10,
        maxFiles: 10,
        

        init: function () {

            var submitButton = document.querySelector("#submit");
            var dz = this;

            //submitButton.addEventListener("click", function () {
            //    wrapperThis.processQueue();
            //});
            submitButton.addEventListener("click", function handler(e) {
                if (dz.getAcceptedFiles().length > 0) {
                    e.currentTarget.removeEventListener(e.type, handler);
                    e.preventDefault();
                    e.stopPropagation();
                    if (dz.getQueuedFiles().length > 0) {
                        alert('send from queue');
                        dz.processQueue();
                    } else {
                        alert('send empty');
                        dz.uploadFiles([]); //send empty 
                    }
                    //dz.processQueue();
                }
            });

+     e.preventDefault();
+     e.stopPropagation();
      if (dz.getAcceptedFiles().length > 0) {
        e.currentTarget.removeEventListener(e.type, handler);
-        e.preventDefault();
-        e.stopPropagation();
