AWS Cloudformation 字符串列表错误

Question

错误： 属性 验证失败：[属性 {/StreamingDistributionConfig/TrustedSigners/AwsAccountNumbers} 的值与类型 {Array} 不匹配]。

我正在尝试在名为 awsAccountNumbers 的参数中获取多个帐户 ID，对此 cloudformation 文档指出此参数必须是 StringList 类型。但是，没有这种类型。我们在 AWS 参数参考中有 String 和 CommaDelimitedList，我得到了提到的错误。我也试过拆分它，但没有帮助。请在下面找到我的代码：

**Parameters Section:** 
  "awsAccountNumbers": {
            "Type": "String",

  }

**Resources Section:** 

   "TrustedSigners": {
                        "AwsAccountNumbers": {
                            "Fn::If": [
                                "withRestrictViewerAccessasYes",
                                {
                                    "Fn::If": [
                                        "withTrustedSignersasSelf",
                                        "882410330966",
                                        [
                                            {
                                                "Fn::Select": [
                                                    "0",
                                                    {
                                                        "Fn::Split": [
                                                            ",",

                                                            { "Ref": "awsAccountNumbers" }

                                                        ]
                                                    }
                                                ]
                                            }
                                        ]
                                    ]
                                },
                                {
                                    "Ref": "AWS::NoValue"
                                }
                            ]
                        },
                        "Enabled": {
                            "Ref": "trustedSignersEnabled"
                        }
                    }

我猜错误指向实际属性 (AwsAccountNumbers) 而不是参数 (awsAccountNumbers)。

AwsAccountNumbers 需要一个列表。它应该像下面这样（未经测试）

"Parameters" : {
  "awsAccountNumbers": {
    "Type": "CommaDelimitedList",
     "Default": "882410330966, 882410330966, 882410330966"
  }

{
    "TrustedSigners": {
        "AwsAccountNumbers": [{
            "Fn::If": [
                "withRestrictViewerAccessasYes",
                {
                    "Fn::If": [
                        "withTrustedSignersasSelf",
                        "882410330966", [{
                            "Fn::Select": [
                                "0",
                                {
                                    "Ref": "awsAccountNumbers"
                                }
                            ]
                        }]
                    ]
                },
                {
                    "Ref": "AWS::NoValue"
                }
            ]
        }],
        "Enabled": {
            "Ref": "trustedSignersEnabled"
        }
    }
}
