AWS Application Load Balancer 无法更新，必须重新创建

Question

使用 CDK，我将 Application Load Balancer 资源的

internetFacing

属性从

true

切换到

false

。当我部署堆栈时，我得到以下输出：

my-stack |  0/19 | 4:47:31 PM | UPDATE_IN_PROGRESS   | AWS::ElasticLoadBalancingV2::LoadBalancer   | ApplicationLoadBalancer (ApplicationLoadBalancerFD56DEE1) Requested update requires the creation of a new physical resource; hence creating one.
my-stack |  0/19 | 4:47:32 PM | UPDATE_FAILED        | AWS::ElasticLoadBalancingV2::LoadBalancer   | ApplicationLoadBalancer (ApplicationLoadBalancerFD56DEE1) Resource handler returned message: "Resource of type 'AWS::ElasticLoadBalancingV2::LoadBalancer' with identifier 'my-lb' already exists." (RequestToken: ..., HandlerErrorCode: AlreadyExists)

更改此属性时是否无法更新LB？
