Test code

(with-current-buffer (find-file-noselect "~/test.org")
  (org-mode)
  (save-excursion
    (goto-char (point-max))
    (org-anki-sync-entry))
  (save-buffer))

The code makes an anki card but can't make ANKI_NOTE_ID property at the heading. Emacs shows the org-fold-region: Calling ‘org-fold-core-region’ with missing SPEC error. And :PROPERTY:\n:END: is printed in the beginning of scratch buffer. I'm not sure. But My guess is that the message is that org seems to try parsing Users' current buffer which is scratch-buffer.
