amazon-web-services - 刷新 AWS FileGateWay 的缓存

Question

我正在尝试刷新AWS FileGateway上的缓存。我已经使用这样的AWSStorageGatewayClientBuilder对象构建了 AWSStorageGateway -

AWSStorageGateway awsStorageGateway = AWSStorageGatewayClientBuilder.standard()
                .withRegion(region)
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .build();

另外，我正在使用它来构建 ARN -

RefreshCacheRequest refreshCacheRequest = new RefreshCacheRequest();
refreshCacheRequest.setFileShareARN("arn:aws:storagegateway:"+region+":"+awsId+":"+shareID); 

ARN 的格式为，

arn:aws:storagegateway:region:account-id:share/share-id 

最后，我像这样刷新缓存 0

awsStorageGateway.refreshCache(refreshCacheRequest);

我得到了这个例外 -

com.amazonaws.services.storagegateway.model.AWSStorageGatewayException: User: arn:aws:iam::12345:user/system/func-user is not authorized to perform: storagegateway:RefreshCache on resource: arn:aws:storagegateway:region:account-id:share-id (Service: AWSStorageGateway; Status Code: 400; Error Code: AccessDeniedException; Request ID:request ID)

我在这里错过了什么吗？

我很确定我拥有的 IAM 访问密钥具有优势。

PS - 我给出的 account-id 是 IAM 的访问密钥
