Terraform import returns Invalid ARN while importing ELB of type classic-CodePudding

I am trying to import an classic load balancer which has been created manually.

The command that I am using

terraform import aws_lb.[lb_name] arn:aws:elasticloadbalancing:[region]:[account_id]:loadbalancer/[lb_name]

the error that i am getting

 aws_lb.[lb_name]: Importing from ID "arn:aws:elasticloadbalancing:eu-west-1:[account_id]:loadbalancer/[lb_name]"...
aws_lb.[lb_name]: Import prepared!
  Prepared aws_lb for import
aws_lb.[lb_name]: Refreshing state... [id=arn:aws:elasticloadbalancing:eu-west-1:[account_id]:loadbalancer/[lb_name]
╷

│       status code: 400, request id: bb8dc4b4-4c02-4883-950b-9e4b5e6fc947

What could be causing this? And, Is it possible to retrieve the ARN of an ELB?

CodePudding user response：

Because you are using Classic Load Balancer which is the previous generation, it basically does not have ARN. I am using the name instead, below mine name is binh-test-clb.

Here is my Terraform resource:

resource "aws_elb" "clb" {
  # (resource arguments)
}

Here is my import command:

terraform import aws_elb.clb binh-test-clb
