I have unit file which looks like below. I am seeing some of the echo are showing up in syslog but not in journalctl. Can someone let me know what is going on?

kafka-systemd-prestart.sh looks like below

# Some other code
echo "completed exiting kafka"
Doing sudo journalctl -u kafka.service looks like below
