You mark a region then jump around the buffer with `org-map-entries'. At
some point the region contains no headline, but you request a subtree
export, hence the error.

But what about the weird export results, where files don't seem to contain the expected content? And is there a better way (than marking and bouncing) to constrain org-map-entries to first-level headings only? 

Well, I can't answer the first question, about the wierd export results, but here at least is a better way, using org-element-map:

(defun mwp-org-export-all-to-org ()
  (interactive)
  (org-element-map (org-element-parse-buffer)'headline
    (lambda (headline)
      (let ((begin (org-element-property :begin headline))
            (level (org-element-property :level headline))
            (commentedp (org-element-property :commentedp headline))
            (tags (org-element-property :tags headline)))
        (unless (or (> level 1)
                    commentedp
                    (member "noexport" tags)
                    ;; I would prefer to get the exclude-tags dynamically but
                    ;; I'm not sure how to do it properly -- need to access exclude-tags somehow
                    ;; (cl-loop for k in (plist-get options :exclude-tags)
                    ;;          thereis (member k  tags))
                    )
          (save-excursion
            (goto-char begin)
            (org-org-export-to-org nil t )))))))
