To disable entering the sleep mode I had to edit the /etc/systemd/logind.conf file and modify the line:
#HandleLidSwitch=suspend
to
HandleLidSwitch=ignore
Additionally, ensure that the file also has this line:
LidSwitchIgnoreInhibited=no
Then restart the OS via:
sudo service systemd-logind restart

add user pi to sudo group "usermod -aG sudo username"
