Problems with ajax on the server

Question

I have an application in ZF2 on Ubuntu server. One of the controllers is triggered from a request ajax.

Locally, the application works normally. However, when going up to the server I started having problems: the request is sent as POST, but I can’t get the data from the controller, because it arrives as GET and with the empty data array.

Would anyone know the problem, since the same code works in local environment?

In the controller the get of data:

$data = $this->getRequest()->getPost()->toArray();
            $request = $this->request;
            $post = array_merge_recursive(
                    $request->getPost()->toArray(), $request->getFiles()->toArray()
            );
            $postData = array();
            $error = array();
            $errSuccess = array();

            //get Query String
            parse_str($post['data'], $postData);

In html I have the following code:

wizard.on("submit", function (wizard) {

            var formData = new FormData();
            formData.append('upload', $('input[type=file]')[0].files[0]);

            var ins = document.getElementById('gallery').files.length;
            for (var x = 0; x < ins; x++) {
                formData.append('gallery[]', $('input[type=file]')[1].files[x]);

            }

            formData.append('data', wizard.serialize());

            $.ajax({
                type: "POST",
                url: '/advertiser/add',
                data: formData,
                cache: false,
                contentType: false,
                processData: false,
                success: function (resp) {
                    if (resp.response == 1) {
                        $(".create-server-name").text($("#nome_razao").val());
                        wizard.submitSuccess();
                        wizard.hideButtons();
                        wizard.updateProgressBar(0);
                        $.each(wizard.cards, function (name, card) {
                            card.el.find("input").val(); // resets all inputs on a card to ""
                        });
                    } else if (resp.response == 2) {
                        var str = '';
                        for (obj in resp.result) {
                            str += "<li>" + resp.result[obj] + "</li>";
                        }
                        $(".create-server-name").text($("#nome_razao").val());
                        $('#errmsg').html(str);
                        console.log(str);
                        wizard.submitSuccess();
                        wizard.hideButtons();
                        wizard.updateProgressBar(0)
                        $.each(wizard.cards, function (name, card) {
                            card.el.find("input").val(); // resets all inputs on a card to ""
                        });
                    } else {
                        var str = '';

                        $('#errmsgerr').html(resp.result);
                        console.log(str);
                        wizard.submitError();
                        wizard.hideButtons();
                        wizard.updateProgressBar(0)
                    }
                },
                error: function () {
                    wizard.submitFailure();
                    wizard.hideButtons();
                },
            });

        });
