Org-ref not working when exporting to LaTeX

[Alessandro Bertulli <alessandro.bertulli96@gmail.com>]

Hi all!

I'm trying to set up an academic workflow, and being unsure about which
framework to use, I gave org-ref a try. However, I can't make it produce
a correct LaTeX PDF file.

I'm going to post my setup in a minute. The
point is: when exporting the org file to LaTeX (C-c C-e l o), a PDF file
gets produced, but it doesn't process the citation keys. For example, in
my file (see below), I got the key "acm:code" literally printed on the
PDF file, in a bold font.

What am I doing wrong?

This is my setup:

init.el ------------------------
(require 'org-ref)
(setq bibtex-completion-bibliography '("~/Library/debug.bib"))
(require 'org-ref-ivy)

(define-key org-mode-map (kbd "C-c ]") 'org-ref-insert-link-hydra/body)

(setq org-latex-pdf-process (list "latexmk -shell-escape -bibtex -f -pdf %f"))

(setq org-ref-insert-link-function 'org-ref-insert-link-hydra/body
      org-ref-insert-cite-function 'org-ref-cite-insert-ivy
      org-ref-insert-label-function 'org-ref-insert-label-link
      org-ref-insert-ref-function 'org-ref-insert-ref-link
      org-ref-cite-onclick-function (lambda (_) (org-ref-citation-hydra/body)))

org-ref-test-file.org ----------------------------

#+title: Org-ref test file
#+bibliography:~/Library/debug.bib
#+latex_header: \usepackage[citestyle=authoryear-icomp,bibstyle=authoryear, hyperref=true,backref=true,maxcitenames=3,url=true,backend=biber,natbib=true] {biblatex}
#+latex_header: \addbibresource{~/Library/debug.bib}
