Why does my React application using 'react-draft-wysiwyg' crash when I set an embedded link in the editor, resulting in an error like 'Invariant Violation: Unknown DraftEntity key: null'? How can I troubleshoot and resolve this issue?
when i set the embedded link it not show any error but when i get the html again from the backend and set it to the editor it show error.

Here is my Code (check the useEffect that generate the error):
