I think you can't use an org-link in a latex src block. You should probably use \eqref{eq:test:2} (probably typed manually). org-ref is not currently clever enough to do that automatically when you inserting in a latex src block.

Hi

Please look at the following lines
eqref:eq:test:1 has been inserted with org-ref-helm-insert-ref-link
it is correctly exported to latex.


\begin{equation}
\label{eq:test:1}
\int
\end{equation}
eqref:eq:test:1


However the same reference in a latex src block is not correctly supported


#+begin_src latex :results latex replace :exports results :eval t
\begin{equation}
\label{eq:test:2}

\end{equation}
eqref:eq:test:2
#+end_src


There is some logic to it, however when I use org-edit-special
to deal with the reference  reftex-reference does do work, but gives the error

Any idea what to do?

Thanks and regards
