Create yjs document from a lexical EditorState

[tobiasandersen]

I'm trying to create a yjs document from a lexical EditorState. I've used this approach to go from a yjs doc to an EditorState. But I'm having issues doing the opposite. This seems to work (building on the withHeadlessCollaborationEditor from the link above):

  const yjsStateUpdate = withHeadlessCollaborationEditor((editor, binding) => {
    const newEditorState = editor.parseEditorState(lexicalJson)
    editor.setEditorState(newEditorState)
    return encodeStateAsUpdate(binding.doc)
  })

But I'm getting this error from yjs, which suggests I'm doing something wrong:

Invalid access: Add Yjs type to a document before reading data.

I don't the warning if I downgrade yjs to the same version used by lexical. Is this a valid approach then?
