Hi all, It appears that Emacs 27 lacks the optional argument for `get-buffer-create`, while `org-element-parse-secondary-string` relies on it. This problem was introduced by the commit 37d6bde27fe2.
Additionally, `org-id-find-id-in-file` also uses `get-buffer-create` with a second argument, but it checks the function and has a condition to call it with or without the argument. Given that `org-compat.el` already contains compatibility functions for different Emacs versions, should we create one for `get-buffer-create` to address this issue? Since `org-compat.el` provides compatibility layers for Emacs 26.1 and later, it's reasonable to assume that Org mode still supports Emacs 27? Thanks, -- yashi
