smartparens' (sp-pair "⟨" "⟩" :wrap "C-*") doesn't work

Question

The following config:

(require 'smartparens)
(smartparens-mode t)
(smartparens-global-mode t)
(sp-pair "⟨" "⟩" :wrap "C-*")

doesn't work. Indeed:

• running C-x C-e on the last line seems to be OK (the minibuffer just contains a very long list starting with ((LaTeX-mode (:open "\\lvert" :close "\\rvert" :trigger "\\lvert" :actions (wrap insert autoskip navigate) :when,

• but, if I run C-*, the *Messages* buffer just displays:

    Mark set
    Wrong type argument: char-or-string-p, nil
  

and the cursor jumps to the end of the following word.

Do you know how to fix this issue?

Caveat

I must admit my config file is not trivial (it is essentially based on [emacs-leuven][1]) but I couldn't test with an empty config. Indeed, despite:

$ ls /home/bitouze/.emacs.d/elpa/smartparens-20220623.1523/smartparens.el
/home/bitouze/.emacs.d/elpa/smartparens-20220623.1523/smartparens.el

in an emacs -Q session, running M-x load-file RET /home/bitouze/.emacs.d/elpa/smartparens-20220623.1523/smartparens.el RET leads to:

Define your pair before enabling the mode. Try:

(require 'smartparens)
(sp-pair "⟨" "⟩" :wrap "C-*")
(smartparens-mode t)
(smartparens-global-mode t)
