    .create(document.querySelector('.ckeditor5'), {
        extraPlugins: [ MyCustomUploadAdapterPlugin ],
    })
    .then(editor => {
        const toolbarContainer = document.querySelector('#toolbar-container');
        toolbarContainer.appendChild(editor.ui.view.toolbar.element);

        let content = $('.ckeditor5').closest('.box-ckeditor5').children('.text-ckeditor5').val();
        editor.setData(content);

        // Note that your request may look different. It is up to you and your editor
        // integration to choose the right communication channel. This example uses
        // a POST request with JSON as a data structure but your configuration
        // could be different.

            // an "error" which has its own "message" that can be passed to reject()
            // in the upload promise.
            //
            // Your integration may handle upload errors in a different way so make sure
            // it is done properly. The reject() function must be called when the upload fails.

            // at least the "default" URL, pointing to the image on the server.
            // This URL will be used to display the image in the content. Learn more in the
            // UploadAdapter#upload documentation.

        // properties which are used e.g. to display the upload progress bar in the editor
        // user interface.

            xhr.upload.addEventListener( 'progress', evt => {

    _sendRequest( file ) {
        // Prepare the form data.
        const data = new FormData();

        data.append( 'upload', file );

        // Important note: This is the right place to implement security mechanisms
        // like authentication and CSRF protection. For instance, you can use
        // XMLHttpRequest.setRequestHeader() to set the request headers containing
        // the CSRF token generated earlier by your application.

        // Send the request.
        this.xhr.send( data );
    }
