Display session error

[georgerabus]

I am installing your dotfile configuration but I get these errors:
Display Session Error: Failed to open display session configuration file

and Oops, an error happened!
..ig/awesome/fishlive/widget/mebox/capsule_theme:lua:18 attepmpt to concatenate a nil value (field fg_focus)

I am using a display manager sddm, how do I workaround to work with that?
Also how do I solve the problem with fishlive package?
I installed all the requirement from the tutorial

# 1. backup your awesomewm configuration first
# 2. git clone repository to ~/.config/awesome
git clone git@github.com:raven2cz/awesomewm-config.git ~/.config/awesome
# 3. ensure prerequsities and dependencies
paru -S rofi # rofi similar app like d-menu
# my used wallpapers and event images
mkdir ~/Pictures/wallpapers && git clone git@github.com:raven2cz/public-wallpapers.git
# my global colorscheme switcher script
# make steps which are described in the raven2cz/global-colorscheme.git project, you need themes for your terminal mainly
mkdir ~/git/github && git clone git@github.com:raven2cz/global-colorscheme.git && cd ~/git/github/global-colorscheme && ./install.sh
# rofi project themes
mkdir ~/.config/rofi && git clone https://github.com/raven2cz/rofi-themes ~/.config/rofi

also how do I find out where does this error come from?
