I tried this on some arbitrary org file (not containing any references) and I
got an error:

I think there is a bug in ox-archive-create-zip:
--8<---------------cut here---------------start------------->8---
...
(switch-to-buffer "*Org ORG Export*")
(insert (format "# archived from %s on %s\n"
org-file-abs-path
(format-time-string "%Y-%m-%d" (current-time))))
;; add bibliography references if they exist.
(org-ref-extract-bibtex-entries)
...
--8<---------------cut here---------------end--------------->8---
because the first thing that org-ref-extract-bibtex-entries does is
--8<---------------cut here---------------start------------->8---
(let* ((temporary-file-directory (file-name-directory (buffer-file-name)))
--8<---------------cut here---------------end--------------->8---
and (buffer-file-name) returns nil on the *Org ORG Export* buffer.
But since you obviously use this code successfully, I wonder why
you don't hit this.
Thanks for any help,
Nick
