Following services are not running: application-locust-follower-1

Hi, I followed the guide and I got this error in my EB Dashboard:

`Following services are not running: application-locust-follower-1`

When I open the locust dashboard, it says the number of slaves is 0. It looks like a slave process is failing to start, but I can't find anything in logs.
If I manually start it by connecting to my instance and running /bin/bash -c "exec /usr/local/bin/locust -f locustfile.py --port=9876 --slave --master-host=$(<.masterIP)", it works, but this is not a viable solution.

Start with the Elastic Beanstalk Dashboard error and the Locust dashboard's slave count, then compare the deployment behavior with the manually run Locust command in the report. Inspect the startup configuration and available logs to identify why application-locust-follower-1 does not start automatically. Done means the follower starts during deployment and Locust reports the expected slave without manual instance access.
