I actually borrowed code from your code example, Because I want to do the following:

#+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)))))

(dolist (link-type (mapcar 'car org-link-parameters))
  (org-link-set-parameters link-type
                           :face #'org-link-beautify-face))
#+end_src

In this way, I can put my code in a union function.

I guess the issue is on the let-binding which invoked ~org-element-property~. But
I can't edebug this function. When I =C-u C-M-x= set edebug on the function, and
toggle ~font-lock-mode~ on Org Mode buffer, this function is not entering edebug.
Don't know how to make Emacs enter this function edebug status.
