I see. I'm running the ConTeXt standalone.

luatex --version
This is LuaTeX, Version beta-0.79.1 (TeX Live 2014/dev) (rev 4972)

In this case I made the error on purpose inserting foo in the blank.

If I want to catch the errors from the log file, is the best way to
grep for "tex error" or something else? In this case the line is not
correct there, but correct when the lines of the file is printed...
