error org-cite-csl-finaliser numberp nil.
This error arises basically in places like (search "something") and then (go-char (matching-line 1)) stuff.
That’s exactly what would happen when org-export calls org-cite-csl-finaliser when #+cite_export: basic is present in the org-mode buffer.
Because there is no match of search of org-cite links in the buffer, so matching-line returns nil, which breaks org-export.
1. solution
if no org-cite link is used, comment out #+cite_export: basic line.
