在CloudWatch事件模式中定义多个环境变量

Question

我正在尝试为CloudWatch设置自定义事件模式规则。到目前为止我提出的是

  EventPattern:
    source:
      - aws.codebuild
    detail-type:
      - "CodeBuild Build State Change"
    detail:
      additional-information:
        environment:
          environment-variables:
            name:
              - "ENVIRONMENT"
            value:
              - !Sub "${Environment}"

这很好用，但我想过滤另一个环境变量。我已经尝试过以下示例，但这不起作用。

示例1 :(我可以保存，但不做任何事情）

  EventPattern:
    source:
      - aws.codebuild
    detail-type:
      - "CodeBuild Build State Change"
    detail:
      additional-information:
        environment:
          environment-variables:
            name:
              - "ENVIRONMENT"
              - "MY_ENV"
            value:
              - !Sub "${Environment}"
              - "true"

示例2 :(错误：事件模式包含空元素或无效元素（只能是非空字符串，布尔值或数字））

  EventPattern:
    source:
      - aws.codebuild
    detail-type:
      - "CodeBuild Build State Change"
    detail:
      additional-information:
        environment:
          environment-variables:
            - name: "ENVIRONMENT"
              value: !Sub "${Environment}"
            - name: "MY_ENV"
              value: "true"

我从CodeBuild获得的模式如下：

{
   "detail":{
      "additional-information":{
         "environment":{
            "environment-variables":[
               {
                  "name":"MY_ENV",
                  "type":"PLAINTEXT",
                  "value":"true"
               },
               {
                  "name":"ENVIRONMENT",
                  "type":"PLAINTEXT",
                  "value":"production"
               }
            ]
         }
      }
   }
}

还有其他想法吗？
