我遵循了这个文件：https://docs.aws.amazon.com/dynamodb-encryption-client/latest/devguide/java-examples.html 并设置加密客户端和Map器来加密项并将其保存到表中，但它不起作用并引发错误，如下所示
堆栈跟踪详细信息：

Map程序代码：

def getDynamoDBMapper(region: String): DynamoDBMapper = {
val cmkArn = "*****************************"
val kms: AWSKMS = AWSKMSClientBuilder.standard().withRegion(region).build()
val cmp: DirectKmsMaterialProvider = new DirectKmsMaterialProvider(kms, cmkArn)
