Coming back to your original issue. Possibly it's enough to just
suppress the error.

You could change the function to

--8<---------------cut here---------------start------------->8---

(defun my/org-agenda-auto-refresh-1 ()
  "Rebuild all agenda views buffers."
  (ignore-errors (org-agenda-redo-all t)))

--8<---------------cut here---------------end--------------->8---
