Cannot convert undefined or null to object when moving dynamic component

[joeyyax]

I have several dynamic zones configured within Strapi that contain CK editor. Everything works great, until you try to move one of those zones up or down. At that point the following error is thrown:

Cannot convert undefined or null to object

This behavior persists with and without a custom config defined in /extensions/ckeditor5/admin/src/config/ckeditor.js.

Hi, I've the same issue, I can prevent the crash by adding some text in the editor before moving the zone.

For me the crash happens only when I move a zone containing CkEditor above an other zone previously added containing CkEditor.

Maybe it can help to fix.

I'm using Strapi 3.6.8 and ckeditor plugin 1.14.0
