How to use eval-defun in emacs config?

Question

I'm encountering this bug invalid org-encode-time. https://www.mail-archive.com/emacs-orgmode@gnu.org/msg146267.html

The bug fixed if I open defun-org-matcher file then use command eval-defun. But the problem exist again if I reclose emacs, and I need to re eval-defun org-matcher again.

Is there a way to automate evaluating defun? I try to use this in my config but it show error. (eval-defun 'org-matcher-time)

Answer 1

The bug is gone after I update emacs to 28.2 and update doom emacs.
