Now I'm back to these issues:

Package scrlayer-scrpage Info: auto-selection of `pagestyleset=KOMA-Script'.
! Undefined control sequence.
<argument> \undefinedpagestyle

l.24 \pagestyle{default}

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

! Undefined control sequence.
l.25 \headsepline
                  =on

This exsurpt starts on line 189 of the attached error file.

Perhaps I misread the KOMA-Script manual, but it advises against using
empty, plain, header, and fancy page styles so only default is left.

And, \headsepline is supposed to work with scrlayer-scrpage.
