Hello,

I’m trying to export a file asynchronously to beamer/pdf, and I have a
strange error. Here is the contents of the *Org Export Process* buffer:

Debugger entered--Lisp error: (void-function org-fold-core--update-buffer-folds)

To make sure I have a reproducible export, I set
org-export-async-init-file to a file with the following contents:

;;; export-init.el --- description -*- lexical-binding: t; -*-

;;; Commentary:

;;; Code:

(setq-default indent-tabs-mode nil)
(setq debug-on-error t)

(require 'ox-latex)

(add-to-list 'org-latex-classes
             '("my-beamer"
               "\\documentclass\[presentation,aspectratio=169\]\{beamer\}
[NO-DEFAULT-PACKAGES]"
               ("\\section\{%s\}" . "\\section*\{%s\}")
               ("\\subsection\{%s\}" . "\\subsection*\{%s\}")
               ("\\subsubsection\{%s\}" . "\\subsubsection*\{%s\}")))

(require 'ox-beamer)

(setq org-latex-listings 'minted)

(setq org-latex-pdf-process
      '("latexmk -pdflatex='%latex --shell-escape -8bit' -pdf -quiet %f"))

(setq org-export-async-debug t)

(provide 'export-init)
;;; export-init.el ends here


I assume the problem is that there is a version mismatch between the org
I’m using to start the export and the org in the async process, but I do
not understand how they would interact. In particular, I don’t
understand why there is a mention of byte-compiled code in the error
trace.

If it matters, the emacs with which I’m initializing the export with is
started with the --init-directory option.

How can I track where this error comes from?

Thanks,

Alan
