在第431行第15行解析块映射时没有找到预期的键

Question

我试图在YAML格式的云形成模板中为elb创建proxy_protocol策略。我收到一个错误“在第431行第15行解析块映射时未找到预期的键”。我在创建CFN模板并传递所需参数时尝试运行AWS cli命令。如何通过CFN模板解决问题并运行AWS cli命令？

Proxy_policy:
          commands:
            01_Enable_proxy:
              command: "$(aws --region", !Ref "AWS::Region", " elb create-load-balancer-policy ",
                                "         --load-balancer-name ", !Ref "AppELB",
                                "         --policy-name ", !Join [ "", [!FindInMap [EnvironmentToPrettyEnvironmentMap, !Ref "Environment", label], ProxyProtocol]] ,
                                "         --policy-type-name ProxyProtocolPolicyType",
                                "         --policy-attributes AttributeName=ProxyProtocol,AttributeValue=True)"
