创建 AWS Elasticsearch 域时出错 - 错误设置策略

Question

我正在尝试设置 AWS Elasticsearch，但无法通过策略设置。
这是政策：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::999999999999:user/xxxxx"
        ]
      },
      "Action": [
        "es:*"
      ],
      "Resource": "arn:aws:es:eu-central-1:99999999999:domain/xyzdomain/*"
    }
  ]
}

这是错误：

CreateElasticsearchDomain: {"message":"Error setting policy: [{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":{\"AWS\":[\"arn:aws:iam::9999999999:user/xxxxx\"]},\"Action\":[\"es:*\"],\"Resource\":\"arn:aws:es:eu-central-1:9999999999:domain/xyzdomain/*\"}]}]“}

这有什么问题吗？
