Hey there,  
i combined the power of org roam with anki-editor to automaticly generate flashcards for the roam files that i create. I did this by creating a custom template that looks like this:  
`(setq org-roam-capture-templates  
'((“d” “default” plain (function org-roam-capture–get-point)  
“%?”  
:file-name "{slug}" :head "#+TITLE: {title}  
#+startup: latexpreview showall

#+ROAM\_ALIAS:  
#+CREATED: %u

- tags ::

\* {title} :PROPERTIES: :ANKI\_DECK: %^{prompt|Master|Russian|Japanese} :ANKI\_NOTE\_TYPE: Basic :END: \*\* Front {title}  
\*\* Back  
"  
:unnarrowed t  
:immediate-finish t)))

(defun push-anki-h()  
(when (org-roam–org-roam-file-p)  
(anki-editor-push-notes)))

(add-hook 'after-save-hook 'push-anki-h)`

The problem i am facing is that it works on my other machine but on the laptop that i am currently using i get the error message:

“Debugger entered–Lisp error: (wrong-type-argument char-or-string-p nil)

I would really aprreciate any help i could get with this because my workflow is really dependent on this 🙂 thank qou
