我想使用 python 中的 boto3 将 DynamoDB 表从一个帐户复制到另一个帐户。 但出现错误

Question

我在 python 中使用下面的代码。

import boto3
import os

dynamoclient = boto3.client('dynamodb', region_name='eu-west-1',
    aws_access_key_id='ACCESS_KEY_SOURCE',
    aws_secret_access_key='SECRET_KEY_SOURCE')

dynamotargetclient = boto3.client('dynamodb', region_name='us-west-1',
    aws_access_key_id='ACCESS_KEY_TARGET',
    aws_secret_access_key='SECRET_KEY_TARGET')

dynamopaginator = dynamoclient.get_paginator('scan')
tabname='SOURCE_TABLE_NAME'
targettabname='TARGET_TABLE_NAME'
dynamoresponse = dynamopaginator.paginate(
    TableName=tabname,
    Select='ALL_ATTRIBUTES',
    ReturnConsumedCapacity='NONE',
    ConsistentRead=True
)
for page in dynamoresponse:
    for item in page['Items']:
        dynamotargetclient.put_item(
            TableName=targettabname,
            Item=item
        )

但是在运行此程序时，我在下面遇到错误。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\ADMIN\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\botocore\paginate.py", line 255, in __iter__
    response = self._make_request(current_kwargs)

    return self._make_api_call(operation_name, kwargs)

    raise error_class(parsed_response, operation_name)
botocore.errorfactory.ResourceNotFoundException: An error occurred (ResourceNotFoundException) when calling the Scan operation: Requested resource not found

我不知道为什么会显示此错误。 我是 python 的新手。 任何帮助，将不胜感激。 感谢！！！

您确定该区域中存在源表吗？
