Howdy,

If it's really using lualatex you need to somehow have it load the luatex85 package and the shellesc package under lualatex. I don't know if your initial file is run under lualatex but you might try to include

\ifx\directlua\@undefined
\else
\RequirePackage{luatex85}
\RequirePackage{shellesc}
\fi

before the \documentclass command. Otherwise you need to see how to have that included in the lualatex call.

I think tikz-fct uses gnuplot and, assuming you have gnuplot in your PATH, using the shell escape provided by the sepdflatexmk engine should do the job.

Good Luck,
