I am following the steps for configure Kamailio IMS : https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/

Getting issue while running pcscf by using below commands [step 17]:

$ mkdir -p /var/run/kamailio_pcscf
$ kamailio -f /etc/kamailio_pcscf/kamailio_pcscf.cfg -P /kamailio_pcscf.pid -DD -E -e
