Hi, the drag and drop functionality works. But I'm having always the same warning when I start to drag:

[Vue warn]: Error in v-on handler: "TypeError: Cannot read property '_vm' of undefined"

found in

---> at DraggableTree.vue

Ignore it if it does not affect the result. I am reconstructing this repo so I will not solve the issue.

I think you are using typescript. If so, give a type to node and childNode.
