laravel horizon elastic beanstalk supervisord having errors - laravel

Question

I a have been trying to setup horizon to run inside an elastic beanstalk instance, and it looks like it works.
supervisorctl status
gets me the following output
horizon RUNNING pid 3435, uptime 0:06:31
but the log prints a successful start then loops an error message and the queue is not working
Horizon started successfully.
sh: line 0: exec: : not found
sh: line 0: exec: : not found <------ This prints like an infinite loop
the horizon queue does work if I start it manually from the ssh shell.
here are my configuration files for EBS
001-cron.config

"/etc/cron.d/mycron":

In your horizon.conf file, try specifying the full path to php:
/usr/bin/php
Like so:
[program:horizon]
process_name=%(program_name)s
command=/usr/bin/php /var/app/current/artisan horizon
autostart=true
autorestart=true
user=root
redirect_stderr=true
stdout_logfile=/var/log/horizon.log
Also note that I am using user=root.
