Re: org-id with ox-html

I cannot have the following minimal example working consistently:

$ cat hello.org

* hello
  :PROPERTIES:
  :ID:       e54113f9-2ad7-4a86-94be-68ffc696de0b
  :END:

  #+INDEX: hello-keyword

  #+begin_src emacs-lisp 
    (org-id-update-id-locations '("hello.org" "bye.org" "theindex.org"))
  #+end_src

  #+begin_src emacs-lisp
    (use-package org-id)
    (setq org-id-link-to-org-use-id t)
    ;; (setq org-html-link-org-files-as-html t)
    (setq org-publish-project-alist
          '(("project-name"
             :base-directory "~/20210814_minex"
             :publishing-directory "~/20210814_minex/html"
             :publishing-function org-html-publish-to-html
             :makeindex t
             )
            ("all" :components ("project-name")
             )
            ))
  #+end_src

  [[id:3c5997f1-205a-437e-8722-d5f52239a207][bye]]

  Some hello paragraph.


$ cat bye.org 

#+HTML_HEAD: <style> .bottom-three {margin-bottom: 5cm;}</style>

* some long section

  #+BEGIN_EXPORT html
  <p class="bottom-three">
     A line.
  </p>
  <p class="bottom-three">

  </p>

  <p class="bottom-three">

  <p class="bottom-three">

  <p class="bottom-three">

  </p>
  #+END_EXPORT


* bye
  :PROPERTIES:
  :ID:       3c5997f1-205a-437e-8722-d5f52239a207
  :END:

  #+INDEX: bye-keyword



  #+begin_example
      [[id:e54113f9-2ad7-4a86-94be-68ffc696de0b][hello]]
  #+end_example


  Some bye paragraph.


Initially it worked, without the `makeindex` and without 
`[[id:e54113f9-2ad7-4a86-94be-68ffc696de0b][hello]]` commented out.

Then with `makeindex` it stopped working consistently. The links became 
broken.

Then, the files `bye.html` and `hello.html` were not generated anymore when 
doing `C-e C-e P a`. Only `theindex.html` was still generated.

So I just definitely have no clue of what is the correct workflow to have that 
project exported correctly to html.
