Sorry, I checked the one thinking the other would work :)

Still getting this with @input instead of file contents,


X-bib-author 1id                : orcid.org/0000-0001-9237-455X
X-bib-pages                     : @input covid19.lastpage
X-bib-filename                  : covid19


with variants of this,

\newcommand{\mjmpagex}{\@@input \mjmbasename.last_page }
%\mjmaddbib{pages}{
\makeatletter
%\@@input \mjmbasename.last\_page 
\mjmaddbib{pages}{\@@input \mjmbasename.last_page }
%\mjmaddbib{pages}{\mjmpagex}
\makeatother
%}
 %}
%\mjmpagex
%\mjmaddbib{pages}{\mjmpagex}
