無法解碼 aws_lb_listener 的計划更改

Question

我正在嘗試使用aws_lb_listener創建一個負載平衡的 EC2 和其中的一部分，該計划可以很好地創建，並且大致如下：

  # aws_lb_listener.app will be created
  + resource "aws_lb_listener" "app" {
      + arn               = (known after apply)
      + id                = (known after apply)
      + load_balancer_arn = "arn:aws:elasticloadbalancing:xxx:xxx:loadbalancer/app/xxx-lb/xxx"
      + port              = 80
      + protocol          = "HTTP"
      + ssl_policy        = (known after apply)

      + default_action {
          + order            = (known after apply)
          + target_group_arn = "arn:aws:elasticloadbalancing:xxx:xxx:targetgroup/tf-xxx-lb/xxx"
          + type             = "forward"
        }
    }

但是在申請時我收到錯誤消息：

Error: failed to decode planned changes for aws_lb_listener.app: error decoding ‘after’ value: an object with 10 attributes is required (9 given)

這是監聽器的實際定義：

resource "aws_lb_listener" "app" {
  load_balancer_arn = aws_lb.app.arn
  port              = "80"
  protocol          = "HTTP"

  default_action {
    type             = "forward"
    target_group_arn = aws_lb_target_group.blue.arn
  }
}

這是負載均衡器的定義：

resource "aws_lb" "app" {
 name               = "xxx"
 internal           = false
 load_balancer_type = "application"
 subnets            = module.vpc.public_subnets
 security_groups    = [module.lb_security_group.this_security_group_id]
}

請幫忙。

Answer 1

嘿發現了問題，這是使用舊 terraform (0.14.08) 和 aws 提供程序版本 (~3.0) 的問題。 將 terraform 更新到 (0.14.10) 和 aws provider (3.36.0) 解決了這個問題....

我認為錯誤消息可能更有幫助......：D
