UniSharp/Laravel Filemanager and TinyMCE integration

I have done a fresh installation of laravel project just to try out tinyMCE with UniSharp filemanager. I have done the UniSharp + tinyMCE instalation following the guide on the github https://github.com/UniSharp/laravel-filemanager.

The WYSIWYG editor is showing up correctly in the browser and I am also able to click the image upload button. However, I get the screen showing Objec not found error.

Object Not Found

My code for the set up looks like this. Original!

<script src="//cdn.tinymce.com/4/tinymce.min.js"></script>
          <textarea name="content" class="form-control my-editor"></textarea>
          <script>
            var editor_config = {
              path_absolute : "/",
              selector: "textarea.my-editor",
              plugins: [
                "advlist autolink lists link image charmap print preview hr anchor pagebreak",
                "searchreplace wordcount visualblocks visualchars code fullscreen",
                "insertdatetime media nonbreaking save table contextmenu directionality",
                "emoticons template paste textcolor colorpicker textpattern"
              ],
              toolbar: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image media",
              relative_urls: false,
              file_browser_callback : function(field_name, url, type, win) {
                var x = window.innerWidth || document.documentElement.clientWidth || document.getElementsByTagName('body')[0].clientWidth;
                var y = window.innerHeight|| document.documentElement.clientHeight|| document.getElementsByTagName('body')[0].clientHeight;

                var cmsURL = editor_config.path_absolute + 'laravel-filemanager?field_name=' + field_name;
                if (type == 'image') {
                  cmsURL = cmsURL + "&type=Images";
                } else {
                  cmsURL = cmsURL + "&type=Files";
                }

                tinyMCE.activeEditor.windowManager.open({
                  file : cmsURL,
                  title : 'Filemanager',
                  width : x * 0.8,
                  height : y * 0.8,
                  resizable : "yes",
                  close_previous : "no"
                });
              }
            };

            tinymce.init(editor_config);
          </script>

Any ideas what could be wrong?

As I said - it is fresh Laravel Project with the tinyMCE and UniSharp guided setup.
