CKEDITOR Get data error editor.getData() with widget plugin

Question

I am using CKeditor version 4.18 and the widget plugin.

I create and use the modal myself with the click event on the toolbar and insert widget into ckeditor HTML.

var element = BuildElementCkeditor(HTML);
state.editor.insertElement(element);
var widget = state.editor.widgets.initOn(element, "module");

But when using the editor.getData() function, an error occurs: enter image description here
