我像这样实现了 ckeditor5，但图像上传按钮不起作用。问题是什么？你能帮我吗？

        .create( document.querySelector( '#editor' ),{

            language: {
                ui: 'tr',content: 'tr'
            },placeholder: 'Makalenizi yazmaya başlayabilirsiniz',heading: {
                options: [
                    { model: 'paragraph',title: 'Paragraf',class: 'ck-heading_paragraph' },{ model: 'heading1',view: 'h1',title: 'Başlık 1',class: 'ck-heading_heading1' },{ model: 'heading2',view: 'h2',title: 'Başlık 2',class: 'ck-heading_heading2' },{ model: 'heading3',view: 'h3',title: 'Başlık 3',class: 'ck-heading_heading3' }
                ]
            }
        } )
        .catch( error => {
            console.log( error );
        } );
