Hi Ihor, 27215ac5b (org-persist: Handle undefined variables in elisp containers, 2022-02-13) added a call to buffer-local-boundp, which was introduced in (what will be) Emacs 28.1.
Could you update org-persist-write:elisp to be compatible with older Emacs versions (e.g., by inlining the short definition and adding a comment about why buffer-local-boundp isn't used)? Thanks.
