On error response body might be None, which causes exception in botocore

tornado's http response on error might have body not set and it will default to None. Botocore expects body to always be string/bytes and will throw exception trying to parse generic error using .strip() on body. https://github.com/boto/botocore/blob/develop/botocore/parsers.py#L270
