Note: Objects have changed outside of Terraform

Terraform detected the following changes made outside of Terraform since the
last "terraform apply" which may have affected this plan:

  # aws_lb.nlb has changed
  ~ resource "aws_lb" "nlb" {
      + arn                              = "arn:aws:elasticloadbalancing:us-west-2:042093043970:loadbalancer/net/dp-dev-sftp-ptm-nlb/b6d1b6a6f6462c28"

Unless you have made equivalent changes to your configuration, or ignored the
relevant attributes using ignore_changes, the following plan may include
actions to undo or respond to these changes.

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  + create
-/+ destroy and then create replacement

Terraform will perform the following actions:
