Answer 1

The first thing to check is that you are connecting to the correct AWS region. If not specified, it defaults to us-east-1 (N. Virginia). A region can also be specified in the credentials file.
In your code, you can specify the region with:
client = boto3.client('autoscaling', region_name = 'us-west-2')
The next thing to check is that the credentials are associated with the correct account. The AWS Lambda function is obviously running in your desired account, but you should confirm that the code running "in linux" is using the same AWS account.
You can do this by using the AWS Command-Line Interface (CLI), which will use the same credentials as your Python code on the Linux computer. Run:
aws autoscaling describe-auto-scaling-groups --auto-scaling-group-names test
It should give the same result as the Python code running on that computer.
You might need to specify the region:
aws autoscaling describe-auto-scaling-groups --auto-scaling-group-names test --region us-west-2
(Of course, change your region as appropriate.)
