Beanstalk: eb deploy erroring out with Invalid length for parameter EnvironmentName, value: 25, valid range: 4-23

Question

I have a Beanstalk environment which has been running since more than a year now. It's running *Python 3.6 running on 64bit Amazon Linux*, which is now deprecated and I need to migrate to Amazon Linux 2 separately.

Out of nowhere, I am not able to do ***eb deploy ***to my environment anymore. It throws an error saying

`ERROR: Parameter validation failed:`
`Invalid length for parameter EnvironmentName, value: 25, valid range: 4-23`

The environment name has never changed after it was created. Why is this error all of a sudden?

My awsebcli version is 30.20.2
