invalid target position in latest version (0.0.27)

[ahmadcore]

hii, iuse this plugin wiht version 0.0.27 (latest), but when i drag and drop control i found warning Invalid target position: Target collection not found, Target is not droppable, accepts [undefined], Component not draggable, acceptable by [undefined] Sorter.js:1019:6

i follow this #21, but i think it suitable for old version not for new version

here my code: header `

<link rel="stylesheet" type="text/css" href="<?=base_url('assets/plugins/mjml/grapesjs-mjml.css')?>" />`

body `

<script type="text/javascript" src="<?=base_url('assets/plugins/grapejs/grapes.min.js?v0.14.27')?>"></script>
<script type="text/javascript" src="<?=base_url('assets/plugins/grapejs/aviary.js')?>"></script>
<script type="text/javascript" src="<?=base_url('assets/plugins/grapejs/mjml/grapesjs-mjml.min.js')?>"></script>
<script type="text/javascript" src="<?=base_url('assets/plugins/grapejs/grapesjs-aviary.min.js')?>"></script>

<script type="text/javascript">
    var images = [];
    var editor = grapesjs.init({
        clearOnRender: true,
        storageManager: {id: 'gjs-mjml-'},
        assetManager: {
            assets: images,
            upload: 0,
            uploadText: 'Not allowed',
        },
        fromElement: true,
        container : '#gjs',
        plugins: ['gjs-mjml']/*,
        pluginsOpts: {
            'gjs-preset-newsletter': {
                modalTitleImport: 'Import template',
                // ... other options
            }
        }*/
    });`
