Bellowing is my source code, it does not work. I'm wondering why?

#+begin_src emacs-lisp
(defun org-link-beautify-face (link)
  "Set link face colors."
  (let ((raw-link (org-element-property :raw-link link))
        (type (org-element-property :type link))
        (path (org-element-property :path link)))
    (pcase type
      ;; ("https" )
      ;; ("http" )
      ("file"
       (if (and (not (file-remote-p path))
                (file-exists-p (expand-file-name path)))
           'org-link 'org-warning)))))

;;; DEBUG
(org-link-set-parameters
 "file"
 :face #'org-link-beautify-face)
#+end_src
