AttributeError: объект 'S3File' не имеет атрибута 'getvalue' при запуске to_csv

Question

Я бегу to_csv Команда для вывода файла на s3 ведро с ServerSideEncryption включено:

to_csv("s3://mys3bucket/result.csv",
       storage_option={'s3_additional_kwargs':
           {'ServerSideEncryption': 'AES256'}})

Я получаю следующую ошибку атрибута:

Я искал эту ошибку, но не смог найти подходящее решение. Есть ли у вас какие-либо идеи?
