Error invalid argument supported for foreach() in Laravel File Manager

I am very beginner in Laravel.

I have this component in my project:

UniSharp/laravel-filemanager

<textarea id="qqq1" name="article-ckeditor" class="ckeditor"></textarea>
<textarea id="qqq2" name="article-ckeditor" class="ckeditor"></textarea>
<script src="http://vanessa.test/vendor/unisharp/laravel-ckeditor/ckeditor.js"></script>
        <script>
            $(".ckeditor").each(function () {
                CKEDITOR.replace( $(this).attr('id'), {

                    filebrowserImageBrowseUrl: 'http://test.test/cms/laravel-filemanager?type=Images',
                    filebrowserImageUploadUrl: 'http://test.test/cms/laravel-filemanager/upload?type=Images&amp;_token=',
                    filebrowserBrowseUrl: 'http://test.test/cms/laravel-filemanager?type=Files',
                    filebrowserUploadUrl: 'http://test.test/cms/laravel-filemanager/upload?type=Files&amp;_token=',
                    height: 800
                });
            });
        </script>

When I open uploader I have path:

http://test.test/cms/laravel-filemanager?type=Images&CKEditor=qqq1&CKEditorFuncNum=1&langCode=pl

and error:

Invalid argument supplied for foreach()

How can I repair this?

I have routing:

Route::get('/laravel-filemanager', '\UniSharp\LaravelFilemanager\Controllers\LfmController@show');
    Route::post('/laravel-filemanager/upload', '\UniSharp\LaravelFilemanager\Controllers\UploadController@upload');
