AWS CLI elasticbeanstalk DescribeEnvironmentHealth is not supported in us-east-1 region

Question

When attempting to execute AWS CLI command for elasticbeanstalk DescribeEnvironmentHealth in us-east-1 i get the follow error 
> An error occurred (InvalidRequestException) when calling the DescribeEnvironmentHealth operation: DescribeEnvironmentHealth is not supported.

here is the command used in us-east-1 region
> aws elasticbeanstalk describe-environment-health --environment-name **** --attribute-names All  --region us-east-1

The same command with EB instance that exist in us-west-2 works.
> aws elasticbeanstalk describe-environment-health --environment-name **** --attribute-names All  --region us-west-2

Answer

Hello there,

The reason for the error "An error occurred (InvalidRequestException) when calling the DescribeEnvironmentHealth operation: DescribeEnvironmentHealth is not supported." is that the [DescribeEnvironmentHealth](https://docs.aws.amazon.com/elasticbeanstalk/latest/api/API_DescribeEnvironmentHealth.html) call is only available for environments configured with [enhanced health](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/health-enhanced.html) reporting. This also explains why the other environment in us-west-2  worked because it must have been configured with enhanced health.

For [basic health](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.healthstatus.html) reporting, you can return the environment health status by using the [describe-environments](https://docs.aws.amazon.com/cli/latest/reference/elasticbeanstalk/describe-environments.html) CLI command.
