org-forward-paragraph doesn't work programatically (called from Lisp)

Hi

I'm trying to unfill/unwrap Org mode files because I switched from auto-fill-mode to visual-line/visual-fill-column mode.

I'd like to harmonize = unfill my already existing (filled) Org mode files. I took the function in

https://www.emacswiki.org/emacs/UnfillParagraph)

and tried the following (from within an emacs lisp buffer):

(let ((fill-column most-positive-fixnum))
  (dolist (f (directory-files-recursively
              "~/directory/with/org/files/" (rx (or ".org" ".outl") eos)))
    (with-current-buffer (find-file-noselect f)
      (while (not (eobp))
        (fill-paragraph)
        (org-forward-paragraph))
      (save-buffer))))

I thought this would iterate over all paragraphs (or org-wise equivalent structures) until end of file is reached and unfill each one of them.

But it doesn't work. The iteration doesn't happen, it somehow doesn't move forward. It works though, if called interactively in an Org mode file.

Why is that, how can I use org-forward-paragraph programmatically?

Thanks
