amazon-web-services - Azure DevOps Cloudformation 更新堆栈使用参数文件失败(##[错误]ValidationError : Parameters: do not exist in the template)

Question

我有一个使用 AWS CloudFormation 更新堆栈任务的 Azure DevOps 构建管道。 CF 模板是指存储在参数文件中的参数。部署时，构建失败，因为任务找不到我在参数文件中引用的参数。

例如文件本身:

[
  {
    "ParameterKey": "EnvironmentParameter",
    "ParameterValue": "dev"
  },
  {
    "ParameterKey": "DBHost",
    "ParameterValue": "xxxxxxxxx.amazonaws.com"
  }
]

该任务引用我的模板参数文件:

这是模板本身的引用:

"dbhostparameter"      : {
    "Type" : "AWS::SSM::Parameter",
    "Properties" : {
        "Name" : "/LCS/Database/host",
        "Type" : "String",
        "Value" : {
            "Fn::Sub" : [
                "${env}", 
                {
                    "env" : {
                        "Ref" : "DBHost"
                    }
                }
            ]
        },

这是失败输出(显示它成功加载模板参数文件)
