I use org-cite with a JSON bibliography and noticed a bug when an entry only has
an "editors" field but no "authors" field. The function
`org-cite-basic—get-author' correctly falls back to using the editors instead of
the authors, but `org-cite-basic--parse-json’ stringifies only the "authors"
field and not the "editors." This creates an error when other functions assume
they got a string from `org-cite-basic—get-author'. The patch fixes the issue by
applying the same transformation to both "authors" and "editors".

As explained in the ChangeLog entry, this points to a more general issue where
`org-cite-basic--get-field' is expected to return nil or a string, but calls
`org-cite-basic--get-entry' that may return an association list. I am not sure
how to fix that since it means converting anything that
`org-cite-basic--get-entry' may return into a string.

Subject: [PATCH] oc-basic.el: Fix wrong type for the editors field when
 parsing JSON.

* lisp/oc-basic.el (org-cite-basic--parse-json): Make sure
`org-cite-basic--parse-json' produces a string for the editors field.
The function `org-cite-basic--get-author' expects a string for both the
"authors" field and the "editors" field.
The conversion to string was only done for the "authors" field in
`org-cite-basic--parse-json'. This patch fixes the issue by applying the
transformation to both "authors" and "editors".

This points to a more general issue where `org-cite-basic--get-field' is
expected to return nil or a string, but calls
`org-cite-basic--get-entry' that may return an association list.

Thanks!

Non-string can only be for JSON bibliographies for fields that are not
supported. `org-cite-basic--get-field' can probably return nil in such
scenarios.

I am attaching tentative patch that will make
`org-cite-basic--get-field' throw an error when the filed value is not a
string.

I would appreciate testing.

Best,
Ihor

Applied, onto main; with minor amendments.
I made the new code not throw error on nil return value.
