You must specify a region .. though I have it specified `--aws_region=us-west-2`

I am getting following error though I have specified the region with --aws_region=us-west-2 parameter

{'sqs_queue_url': 'https://sqs.******.amazonaws.com/********/********', 'kubernetes_deployment': 'torpid-alligator', 'kubernetes_namespace': 'default', 'aws_region': 'us-west-2', 'poll_period': 10, 'scale_down_cool_down': 30, 'scale_up_cool_down': 10, 'scale_up_messages': 20, 'scale_down_messages': 10, 'max_pods': 5, 'min_pods': 1}

@harshadyeola I ran into this as well. The fix is to add an additional environment variable (AWS_DEFAULT_REGION) to the deployment. e.g.:

  template:
    spec:
      containers:
        env:
        - name: AWS_DEFAULT_REGION
          value: us-east-1
