AWS KMS 解密错误 Credstash

Question

我的 aws 账户在 us-west-2 区域。并且在该帐户中创建的 KMS 密钥具有 ARN arn:aws:kms:us-east-1::key/。在我的节点模块中，我使用 Credstash 来解密使用 KMS 密钥加密的密钥。

var credstash = new Credstash({ 'table': 'tablename', 'awsOpts': { 'region':'region' } });
let secret = credstash.getSecret({name: 'keyname'}).then(result =>{
    console.log(result);
});;

我低于异常。

 "The ciphertext refers to a customer master key that does not exist,
 does not exist in this region, or you are not allowed to access"

以下是 sls 文件中的 IAM 策略。

Effect: "Allow"
      Action: ["kms:Decrypt"]
      Resource: [
         Fn::Join: ["", [ "arn:aws:kms:us-east-1:accountid:key/",{"Fn::Sub": "kmskey"}]]
      ]

解决此问题的任何指示都会有很大帮助
