Loading jupyter among the babel languages produces an error

[arael]

Here is my config:

(org-babel-do-load-languages 'org-babel-load-languages '(
    (gnuplot . t)
    (latex . t)
    (python . t)
    (jupyter . t)
    (shell . t)
    (dot . t)))

Here is the error:

Debugger entered--Lisp error: (json-number-format 5)
  signal(json-number-format (5))
  json-read-number()
  json-read()
  json-read-from-string("0.00s - Debugger warning: It seems that frozen mod...")

  eval-last-sexp(nil)
  funcall-interactively(eval-last-sexp nil)

I had to comment the (jupyter . t) line, otherwise I cannot export org files to anything, including pdf files.

If the jupyter line is not commented and I try to export an org file, for example to a pdf, I get this error in the Messages buffer:

json-read-number: Invalid number format: 5

Emacs version: 28.2 OS: Arch Linux

I have experienced the same issue as well

[danielpopescu]

the documentation clearly states it needs to be added last in the list... (org-babel-do-load-languages 'org-babel-load-languages '( (gnuplot . t) (latex . t) (python . t) (shell . t) (dot . t) (jupyter . t) ))

is that helping?

[arael]

@danielpopescu I tried this but it does not solve the problem. I get the same error that I have posted in the initial report. Thank you for the suggestion though.

same here

so from my end, it looks like commenting out the org-babel-jupyter-override-src-block will solve the issue. Here's my current configuration:

(use-package! jupyter
  :config
  (org-babel-do-load-languages
   'org-babel-load-languages
   '((emacs-lisp . t)
     (python . t)
     (jupyter . t)))
  (setq ob-async-no-async-languages-alist '("jupyter-python" "jupyter-julia")))

;; (use-package ob-jupyter
;;   :config
;;   ;; use LANG intead of jupyter-LANG in src block
;;   (org-babel-jupyter-override-src-block "python")
;;   (org-babel-jupyter-override-src-block "julia"))
