Fails when scanning regions that are not enabled #9

Closed gberardi-pillar closed 4 years ago

gberardi-pillar commented 4 years ago

The script asks for a list of regions and then iterates through them.

The following occurs if you don't have all regions enabled:

$ python clear_lambda_storage.py 
Scanning ap-east-1 region
Traceback (most recent call last):
  File "clear_lambda_storage.py", line 191, in <module>

    for lambda_function in function_generator:

    response = lambda_client.list_functions()

    raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (UnrecognizedClientException) when calling the ListFunctions operation: The security token included in the request is invalid.

When I run:

aws s3 ls

I see output that indicates my security token is fine.

When I check ap-east-1 in the AWS Management Console, it says I need to enable it.

If I hardcode the script to use a specific region I know is enabled (us-east-1), the script runs and deletes old lambdas just fine.
