BACKOFF Exited too quickly (process log may have details)

I have installed supervisor on AWS EB via SSH the server is

PHP 7.4 | running on 64bit Amazon Linux 2 | Laravel 7.0

When I put the config of workers in /etc/supervisord.d/a-dev.conf file

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /var/app/current/artisan queue:work sqs --sleep=3 --tries=3 
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
user=root
numprocs=8
redirect_stderr=true
stdout_logfile=/var/app/current/storage/worker.log
stopwaitsecs=3600

then check the status of workers via

[ec2-user@ip-XXX-XX-21-0 storage]$ sudo supervisorctl status

laravel-worker:laravel-worker_00   BACKOFF   Exited too quickly (process log may have details)
laravel-worker:laravel-worker_01   BACKOFF   Exited too quickly (process log may have details)

laravel-worker:laravel-worker_06   BACKOFF   Exited too quickly (process log may have details)

I got this error in log file

Missing required client configuration options:

  (e.g., "us-west-2"). A list of available public regions and endpoints can be
