Почему Boto3 выдает ошибку создания s3?

Question

Почему Boto3 выдает ошибку создания s3? Я пытаюсь создать корзину, но получаю несколько разных ошибок. Я пробовал много способов решить эту проблему, но пока не смог. Благодарю всех за помощь и время.

Ниже вы можете найти код и ситуацию

Мой код ниже:

class BucketManager:  # help us to organized data and code together  
    """"Manage an s3 Bucket."""  
    CHUNK_SIZE = 8388608  
    def __init__(self, session):  # init works as constructor on this line  
        """Crete a BucketManager object."""  
        self.session = session  
        self.s3 = self.session.resource("s3")  
        self.transfer_config = boto3.s3.transfer.TransferConfig(

Похоже, что в этом коде self.session.region_name не определено:

            s3_bucket = self.s3.create_bucket(  
                Bucket=bucket_name,  
                CreateBucketConfiguration= \  
                    { "LocationConstraint": self.session.region_name  
                },  
            )
