Laravel Horizon Not enough arguments (missing: "connection")

Question

Before I use defaults name of supervisor-1 on config/horizon.php. And then, I changed the name to more clear name: supervisor-high-priority, supervisor-long-timeout, etc.

But why, supervisor.d keep call this command.

Starting Artisan command: horizon:supervisor
{
input: 'horizon:supervisor' 'somewebsites-webserver-production-V4ir:supervisor-1' --workers-name=default --balance=off --max-processes=10 --min-processes=1 --nice=0 --balance-cooldown=3 --balance-max-shift=1 --parent-id=17403 --backoff=0 --max-time=0 --max-jobs=0 --memory=128 --queue= --sleep=3 --timeout=60 --tries=0 --rest=0
}

Resulting error

Symfony\Component\Console\Exception\RuntimeException
Not enough arguments (missing: "connection").

I already tried, to run artisan config:clear, cache:clear. Restart the supervisor service with sudo systemctl restart supervisor.service

sudo supervisorctl reread
 
sudo supervisorctl update
 
sudo supervisorctl start horizon

But, supervisor keep call that supervsor-1.

Here is my supervisor configuration:

[program:horizon]
command=php ./artisan horizon
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
redirect_stderr=true
directory=/home/somewebsites/webseiten/somewebsites/current
user=manobo
stdout_logfile=/home/somewebsites/webseiten/somewebsites/current/storage/logs/horizon.log
stopwaitsecs=36000

When I run artisan:list, I can see the supervisor-1, that I dont have it on config/horizon.php.

I suspect, horizon cached older configuration, that can not be cleared even after running artisan config:clear.

Do I miss some steps here? Thanks before.

EDIT: I found my mistake. On config/horizon. I didn't define the environments where the supervisor will be (production, staging, etc). Therefore the defaults supervisor-1 from Horizon package will be added.
