elpy-snippet-init-assignments - "Symbol’s value as variable is void: start-point"

[lu-pl]

Emacs version: 29.2
yasnippet version: 20240124.258 (Melpa)

Snippets using elpy-snippet-init-assignments expand to error output "Symbol’s value as variable is void: start-point".

E.g.

# -*- mode: snippet -*-
# name: init
# key: init
# group : definitions
# --

def __init__(self${1:, args}):
    ${1:$(my/elpy-snippet-init-assignments yas/text)}

expands to

def __init__(self, args):
    Symbol’s value as variable is void: start-point

As a quick fix replacing start-point with (point) appears to work:

(defun fix/elpy-snippet-init-assignments (arg-string)
  "Return the typical __init__ assignments for arguments in ARG-STRING."
  (let ((indentation
	 (make-string
	  (save-excursion
	    (goto-char (point))
	    (current-indentation))
	  ?\s)))
    (mapconcat
     (lambda (arg)
       (if (string-match "^\\*" arg)
	   ""
	 (format "self.%s = %s\n%s" arg arg indentation)))
     (elpy-snippet-split-args arg-string) "")))

What/where is my/elpy-snippet-init-assignments?
It sounds like the error is coming from that function, which is not part of YASnippet, AFAICT.
