How to understand which control sequence in undefined in “Undefined control sequence.” message?
I got "Undefined control sequence." message, but from ...sdir{directlua{tex.sprint(lfs.currentdir())} I do not understand, on which control sequence LuaLaTeX refers:
How can I explore it?
The MWE is
documentclass[a4paper, twoside]{ltjsarticle}
usepackage{luatexja-fontspec}
edefcurrfileabsdir{directlua{tex.sprint(lfs.currentdir())}/}
begin{document}
done
end{document}

@AlanMunn, Thank you for try. Did you compile by LuaLaTeX? It's interesting, what I missed. I'll upload a screencast later.

@Kurt, no. Anyway, the cause is not here because I compile other LuaLaTeX project without errors on same PC.

The undefined control sequence is Users which is part of the path. Even though here is meant to be the path separator, LuaTeX doesn't know that and just feeds the path with the currently active catcodes back to TeX, where happens to be the escape characters. Luckily, you can tell tex.sprint to use a different catcode table using an optional argument. To use verbatim catcodes (everything is catcode 12, except space which retains catcode 10) use the catcode table with number -2.

The undefined control sequence is the thing just before the line break:
documentclass{article}
begin{document}
quadacommandthatdoesntexistquad
end{document}
Has the output:
! Undefined control sequence.
<*> quadacommandthatdoesntexist
quad
In your case, that appears to be Users, which may suggest that TeX is trying to read a Windows path and interpreting the as beginning a command. You'll probably need a package that can navigate Windows directories.
