Can compile with luatex in the command line but not in AUCTEX in emacs

Question

As stated in the title, my document compiles successfully with lualatex file.tex in the command line but not when in emacs using AUCTEX, executing C-c C-c. I'm using a Mac; Tex Live; and auctex v12.1.1.

I am aware of this answer: https://tex.stackexchange.com/a/21212/103829 and have inserted the following at the bottom of my .tex file:

%%% Local Variables: 
%%% coding: utf-8
%%% mode: latex
%%% TeX-engine: luatex
%%% End:

Does it work if you manually M-x TeX-engine-set <ret> and set it to luatex? — Henri Menke, Jun 14 '18 at 04:26
Then post a minimal working example (MWE) and the log file which C-c C-c in Emacs created. — Henri Menke, Jun 14 '18 at 05:23

Your MWE is not like what you post, it contains:

%%% Local Variables: 
%%% coding: utf-8
%%% mode: latex
%%% TeX-engine: luatex
%%% TeX-master: ""
%%% End:

Remove the evil line with TeX-master. Or replace it with

%%% TeX-master: t

if needed.

Personnally I have had for decades

(setq TeX-one-master '"\"<none>\"")

in my .emacs to prevent AUCTeX modifying my file contents.

It could be that in the past AUCTeX did not have the default t setting for TeX-master which it seems to have now. I recall how painful it was at first when systematically my buffer ended up with some added lines for "Local Variables" at bottom, which got me really annoyed as I did not want to change modification date of a visited .tex file, typically. – Jun 14 '18 at 14:29
In my case I needed the %%% TeX-master: t for it to work. But I added (setq TeX-one-master '"\"<none>\"") to my .emacs file to prevent annoying additions to the bottom of files! – Oliver Angelil Jun 14 '18 at 22:06
