I'm having trouble with citar in org-mode. With a simple .bib file, `org-cite-insert` works fine without citar, but whenever I set `(org-cite-insert-processor 'citar)`, like explained here https://github.com/emacs-citar/citar?tab=readme-ov-file#org-cite , then org-cite-insert just says `Aborted`. I tried to debug using `debug-on-entry` for the function `org-cite-insert`, but that is just endless sequence of commands. 

 - org - v9.6.15
 - citar - v20240419.2232 
 - emacs v29.4

tried both on mac and ubuntu with the same result.

How could I continue, like get proper backtrace instead of message "Aborted"?

Update:
trying with edebug (edebug-defun), it gets to the choice in minibuffer, which shows `References: (0/1):`, but there no matter if I try TAB, Enter or something else, it just gets aborted.
