Root Cause

AWS region not configured. Set via env var, config file, or SDK parameter.

Workarounds

  1. 95% success Set AWS_DEFAULT_REGION env var: export AWS_DEFAULT_REGION=us-east-1 
    export AWS_DEFAULT_REGION=us-east-1

    Sources: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html

  2. 92% success Configure in ~/.aws/config: aws configure set region us-east-1 
    aws configure set region us-east-1

    Sources: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html

  3. 88% success Set in boto3 client: boto3.client('s3', region_name='us-east-1') 
    boto3.client('s3', region_name='us-east-1')

    Sources: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/configuration.html

Dead Ends

Common approaches that don't work:

  1. Hardcode us-east-1 everywhere 65% fail

    Breaks for resources in other regions and couples code to region

  2. Set region in every boto3 call 55% fail

    Verbose and easy to miss — set it once globally
