Debug Output

Expected Behavior

Modifying a aws_alb_listener_rule should update the listener rule as planned

  # aws_alb_listener_rule.oidc_auth_rules[0] will be updated in-place
  ~ resource "aws_alb_listener_rule" "oidc_auth_rules" {
      ....
          ~ authenticate_oidc {
             ...

                on_unauthenticated_request          = "authenticate"
              ~ scope                               = "openid email profile" -> "openid profile"
            }
        }
       ....

        condition {
            field  = "query-string"
            values = []

            query_string {
                key   = "profile"
                value = "MPM.Search"
            }
        }
    }

Actual Behavior

Error: Both field and values must be set in a condition block

on load_balancer.tf line 40, in resource "aws_alb_listener_rule" "oidc_auth_rules":
40: resource aws_alb_listener_rule "oidc_auth_rules" {

Steps to Reproduce

1. Create a aws_alb
2. Create a aws_alb_listener
3. Create a aws_alb_listener_rule that contains a condition of type query string
4. terraform apply
5. Modify the aws_alb_listener_rule to trigger a inplace update (changing the scope for example)
6. terraform apply
