Start with the AWS CloudFormation Create/Update Stack task described in the log, using Api.yaml, the us-east-1 region, and the standard access/secret-key service endpoint. Compare the credential configuration with the reported SignatureDoesNotMatch failures during stack existence checks and template upload; done means the task completes without those signature errors.
