I would rephrase this:
>The AWS region could not be identified automatically from the environment.
Automatic AWS region retrieval is only available when the consumer is run in
AWS environments, which is recommended for production usage to avoid
cross-region network traffic. When executed in non-AWS environments, please set
the region manually using the property AWSConfigConstants.AWS_REGION.
