The Scheme log is not separate from the LilyPond log. Most likely, the
error message is there, but not right next to 'GUILE signaled ...'.
For example:


GNU LilyPond 2.22.2
Processing `-'
Parsing...
%%%% First message is here:
-:3:2: error: GUILE signaled an error for the expression beginning here
#
 (+ 2 '())
Interpreting music...
Preprocessing graphical objects...
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...
Converting to `-.pdf'...
%%%% Actual error message here:
Wrong type: ()
