init.d script won't rerun python script on error - shell

Question

I am new to shell scripting and am having a bit of an issue when it comes to rerunning my script. My script is located here /etc/init.d/receiver and when I use the following command sudo systemctl start receiver, I get the following error,
Job for receiver.service failed because the control process exited with error code.
See "systemctl status receiver.service" and "journalctl -xe" for details.
To test out the "retry" on crash, I purposely made a line in my python script that is being called to crash the program. That line is someError = 'error. Otherwise, the shell script which calls the python script runs with no issue but the whole point of this init.d shell script is to rerun the py script in case of an error and to start at startup. Here is my code,
#!bin/sh
### BEGIN INIT INFO
# Provides: Test_receiver.py
# Reqired-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 3 4 5 6
# Default-Stop: 0
# Short-Description: Rabbit consumer script Test_receiver.py
### END INIT INFO
set -e
# /etc/init.d/startup: start and stop the Test_receiver.py script
# no file /etc/default/startup for added config at this time
. /lib/lsb/init-functions
cd /home/cschoom/Security/src
run_receiver(){
log_action_begin_msg "Starting Test_receiver.py"
log_file=/home/cschuma1/otherfile.txt
python Test_receiver.py 2>> $log_file
retval=$?
if [ $retval == "0" ]; then
echo "success"
log_action_cont_msg "No issues"
else
echo "failure" >> $log_file
log_failure_msg "ERROR WITH TEST_RECEIVER `date`"
sleep 5
run_receiver
fi
}
case "$1" in
start)
run_receiver
;;
stop)
echo "killing Test_receiver script"
log_action_begin_msg "Killing Test_receiver.py"
kill $(pgrep -f 'python Test_receiver.py')
;;
restart|force-reload)
log_action_begin_msg "Reloading Peach_receiver.py"
run_receiver
;;
*)
echo "Usage /etc/init.d/receiver (start|stop|restart|force-reload)"
exit 1
;;
esac
exit 0
`
All I am trying to do is run Test_receiver.py, grab the return value, and based off that return value, either rerun the run_receiver function which calls my python script again or exit with 0 return code. This is a rabbitmq consumer script which will just run endlessly so I would like to rerun the python script as the fault will likely not be with the script but instead with what is being tested. (my python script runs tests, like nmap, on other machines). Any help would be appreciated. Thanks
