Org-back-to-heading: Before first headline at position 1 in buffer

Troubleshooting
#1

I installed org-roam and followed the video with

(use-package org-roam
  :ensure t
  :init
  (setq org-roam-v2-ack t)
  :custom
  (org-roam-directory "~/RoamNotes")
  :bind (("C-c n l" . org-roam-buffer-toggle)
	 ("C-c n f" . org-roam-node-find)
	 ("C-c n i" . org-roam-node-insert))
  :config
  (org-roam-setup))

but when I try `org-roam-node-find` I get the message above.
#2

Huh - I restarted emacs and the error went away
