Unable to access 'load_balancer_arn' property from 'aws_lb_listener' data query

[bhales]

Terraform Version

Terraform: v0.10.8
AWS Provider: v1.9-1.15

Affected Resource(s)

• aws_lb_listener

Terraform Configuration Files

The terraform below was able to use a listener arn as input to get details about the associated load balancer. The worked until AWS provider v1.9 and is still an issue with the latest version at this time(v1.15). The result from v1.9 and up is an error saying 'load_balancer_arn' is not an attribute of the listener(see below).

data "aws_lb_listener" "selected" {
	arn = "${var.alb_listener_arn}"
}

data "aws_lb" "selected" {
	arn  = "${data.aws_lb_listener.selected.load_balancer_arn}"
}

Expected Behavior

I would expect the query to function as it previously did and return the load balancer arn. Similar to the AWS CLI command:
aws elbv2 describe-listeners --listener-arns <arn>

Actual Behavior

Error: Error running plan: 1 error(s) occurred:

* module.sts.data.aws_lb.selected: 1 error(s) occurred:

* module.sts.data.aws_lb.selected: Resource 'data.aws_lb_listener.selected' does not have attribute 'load_balancer_arn' for variable 'data.aws_lb_listener.selected.load_balancer_arn'

Steps to Reproduce

Have a simple terraform that queries for a listener and attempt to access the 'load_balancer_arn' attribute.

Important Factoids

This worked from v1.2 through v1.8. After a little digging this appears to be associated with the change to add another method of querying for a listener via load balancer name and port. Associated issues below.

These issues appear to be related but I'm not certain.

Hi @bhales 👋 Thank you very much for this bug report. Indeed this was a regression that was introduced. @loivis and I quickly pushed through the fix for this in #4317, which will release in v1.16.0 of the AWS provider, likely in two days or so.

That's great. Thanks for the quick turnaround.

This has been released in version 1.16.0 of the AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
