Как исправить ошибку 404 в wordpress admin-ajax?

Я пытаюсь настроить отправку данных расширенные настраиваемые поля pro, которые включают поле изображения, с использованием ajax без использования собственной отправки, предоставляемой acf.

Это может показаться изобретением колеса, но это единственный способ, которым это работает для моего варианта использования, который является многоступенчатая форма. По умолчанию acf не предоставляет для этого функциональных возможностей.

В настоящее время я получаю ошибку ЗАПИСЬ https://dev.energypages.com/wp-admin/admin-ajax.php 400 (), и я не уверен, почему, я был бы очень признателен, если бы свежий взгляд взглянул на мой код и посмотрел, могут ли они найти какие-либо проблемы, которые я не могу.

Также мне не удалось получить данные изображения вместе со строковыми данными.

Javascript:

$(".nexttwo").on('click', function() {
  resetErrors();

  current_fs = $(this).parent();
  next_fs = $(this).parent().next();
  var comid = getUrlParameter('cid');

  var companydata = new FormData(this);
  companydata.append("comdata", "company_info");
  companydata.append("cid", comid);

  $.ajax({
    url: ajaxurl,
    processData: false,
    contentType: false,
    dataType: 'json',
    method: 'post',
    data: companydata,
    success: function(data) {
      console.info(JSON.stringify(data));
      for (var i = 0; i < data.length; i++) {
        var status = data[i].code;
        var field = data[i].field;
        var message = data[i].msg;
        //var comid = data[i].cid;

        if (status == "200") {
          //successful validation
          if (animating) return false;
          animating = true;

          //activate next step on progressbar using the index of next_fs
          $("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

          //show the next fieldset
          next_fs.show();
          //hide the current fieldset with style
          current_fs.animate({
            opacity: 0
          }, {
            step: function(now, mx) {
              //as the opacity of current_fs reduces to 0 - stored in "now"
              //1. scale current_fs down to 80%
              scale = 1 - (1 - now) * 0.2;
              //2. bring next_fs from the right(50%)
              left = (now * 50) + "%";
              //3. increase opacity of next_fs to 1 as it moves in
              opacity = 1 - now;
              current_fs.css({
                'transform': 'scale(' + scale + ')'
              });
              next_fs.css({
                'left': left,
                'opacity': opacity
              });
            },
            duration: 800,
            complete: function() {
              current_fs.hide();
              animating = false;
            },
            //this comes from the custom easing plugin
            easing: 'easeInOutBack'
          });
        } else {
          var msg = '<label class = "acf-notice -error acf-error-message error" for = "' + field + '">' + message + '</label>';
          $('input[name = "' + field + '"], select[name = "' + field + '"]').addClass('acf-error').before(msg);
        }
      }
    }
  });
});
