这不是您引用 cloudformation 资源的方式吗？

Question

使用 deisgner 构建模板，Cloudformation 给出了一个

“resourcesToImport.1.member.resourceIdentifier”中的值“{LoadBalancerArn=}”未能满足约束：映射值必须满足约束：[成员的长度必须小于或等于 2048，成员的长度必须大于或等于1];

下面的代码。对 8 个不同的资源有 8 个相同的错误。知道出了什么问题吗？

       "ELB": {
        "Type": "AWS::ElasticLoadBalancingV2::LoadBalancer",
        "Properties": {...},
        "Metadata": {...}
        },
        "DeletionPolicy": "Retain"
    },
    "Listener": {
        "Type": "AWS::ElasticLoadBalancingV2::Listener",
        "Properties": {
            "DefaultActions": [
                {
                    "Type": "fixed-response",
                    "FixedResponseConfig": {
                        "ContentType": "text/plain",
                        "MessageBody": "Fixed Response",
                        "StatusCode": "200"
                    }
                }
            ],
            "LoadBalancerArn": {
                "Ref": "ELB"
            },
            "Protocol": "HTTP"
        },
        "Metadata": {
            "AWS::CloudFormation::Designer": {...}
        },
        "DependsOn": [
            "ELB"
        ],
        "DeletionPolicy": "Retain"
    }

Answer 1

至少，DeletionPolicy 处于错误的级别：

       "ELB": {
        "Type": "AWS::ElasticLoadBalancingV2::LoadBalancer",
        "Properties": {...},
        "Metadata": {...}
        },
        "DeletionPolicy": "Retain"

应该在这里：

       "ELB": {
        "Type": "AWS::ElasticLoadBalancingV2::LoadBalancer",
        "Properties": {...},
        "Metadata": {...}
        "DeletionPolicy": "Retain"
        },
