Problem

You are unable do upload, copy or download artifacts due to Tasks for AWS encountering an AmazonS3Exception: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'us-west-2'.

Solution

Despite the S3 bucket namespace being global, the Amazon S3 Object task uses regional API endpoints and thus requires the selected region to match the one where the bucket is actually located in.

You need to adjust the selected region accordingly:

  1. Identify the bucket's actual location, which is denoted as the expected one in the error message
    ('us-west-2' in this example)

  2. Adjust the selected region in the Amazon S3 Object task configuration to match the bucket's actual location
