wrong-type-argument listp when exporting example file

[andreas-h]

I'm trying to get this to work, but am running into issues with the example file.

I have this in my init.el:

(load-file "~/.emacs.d/external/ox-ipynb/ox-ipynb.el")
(require 'ox-ipynb)

Now, when I open the example.org file and press C-c C-e n b, I get the following error:

Debugger entered--Lisp error: (wrong-type-argument listp #("John Kitchin" 0 12 (:parent (#1))))
  org-element-set-contents(#("John Kitchin" 0 12 (:parent (#0))))

(add-to-list 'load-path "~/.emacs.d/external/ox-ipynb/")
(require 'ox-ipynb)
