I'm making a book with the koma-script (scrbook) class and I need to add a minitoc at the start of every part and chapter. I found a solution with this post, however it doesn't work with the greek language from babel.
Here is a minimal example:
\documentclass[fontsize=10pt,open=any,twocolumn]{scrbook}[2019/10/12]% needs version 3.27 or newer
\usepackage[greek]{babel}
\providecommand*{\Ifstr}{\ifstr}% added because of changes in upcoming KOMA-Script version 3.28 and \ifstr replaced by \Ifstr in the code (see https://komascript.de/faq_deprecatedif)
\usepackage{blindtext}
\usepackage{xcolor}
\usepackage{scrwfile}% avoid trouble with the limited number of write handles
\usepackage{xpatch}
\colorlet{partcolor}{blue}
\addtokomafont{partprefix}{\color{partcolor}}% change color of part prefix
\addtokomafont{part}{\normalcolor}% use normal color for part title
%\renewcommand*\partformat{\partname~\thepart}% if you want to remove \autodot from the definition
\RedeclareSectionCommand[
tocdynnumwidth=true,%
tocbeforeskip=1em,
tocindent=1.5em
]{part}
\RedeclareSectionCommand[
beforeskip=0pt,
afterindent=false,
afterskip=2\baselineskip,
tocdynnumwidth,
tocbeforeskip=1em plus 1pt minus 1pt,% add some glue
toclinefill=\TOCLineLeaderFill
]{chapter}

afterskip=.5\baselineskip,

\RedeclareSectionCommand[
beforeskip=.5\baselineskip,
afterindent=false,
afterskip=.25\baselineskip,
tocindent=7em,

\RedeclareSectionCommand[

tocnumwidth=5em
]{paragraph}
\RedeclareSectionCommand[

tocnumwidth=6em
]{subparagraph}
\RedeclareSectionCommands

This puts an error
! Incomplete \iffalse; all text was ignored after line 127.
<inserted text>
\fi
Using the polutonikogreek language instead of the greek language puts the same error. I suspect that this is related to the Ifstr\ifstr problem in KomaScript but when the greek language works in a complete book, it doesn't bear this minitoc approach? I need to write some sentences in greek, not the complete book.
