amazon-web-services - CloudFormation参数模板错误: Parameter is non alphanumeric

Question

我正在使用

aws cloudformation validate-template --template-body file://template.json

然后出现错误:

CloudFormation Parameter Template Error : Parameter is non alphanumeric

以下代码显示了我的 params.json 和 template.json 文件。

params.json

[
    {
        "ParameterKey": "name_for_abc",
        "ParameterValue": "abc"
    }
]

模板.json

{
    "AWSTemplateFormatVersion": "2010-09-09",
    "Transform": "AWS::Serverless-2016-10-31",
    "Description": "some text",
    "Parameters": {
        "name": {
            "Description": "name_of_abc",
            "Type": "String"
        }
    },
    "Resources": {
        "LambdaFunctionAuto": {
            "Type": "AWS::Serverless::Function",
            "Properties": {
                "Environment": {
                    "Variables": {
                        "name_of_abc": {
                            "Ref": "name_of_abc"
                        }
                    }
                }
            }
        }
    }
}

要解决此问题，请将 params.json 文件和 Parameters 中的参数 name_of_abc 重命名为 nameofabc > CloudFormation 模板的部分。

来自AWS documentation :

Each parameter must be given a logical name (also called logical ID), which must be alphanumeric and unique among all logical names within the template.
