botocore.exceptions.InvalidRegionError: Provided region_name 'us-west-2 us-east-1 us-east-2 sa-east-1 eu-west-1 eu-central-1 ap-south-1' doesn't match a supported format.

Start by reproducing the command from the traceback, then read awslogs/bin.py and awslogs/core.py around argument handling and boto3_client. The report does not specify the intended behavior or name a test, so the expected region-input behavior must be clarified before defining done.
