Apply fails with "Launch configuration name not found"

[bilalaslam]

I saw a report of this issue on IRC didn't see an issue on Github, so here goes. I am seeing terraform apply fail with a ValidationError. This may be some sort of eventual consistency thing as Mitchell suggested.

I verified through the AWS console that the launch configuration named coreos indeed exists.

Error applying plan:

1 error(s) occurred:

* ValidationError: Launch configuration name not found - Launch configuration coreos not found

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

Offending .tf file:

resource "aws_security_group" "coreos" {
    name = "coreos"
    description = "CoreOS security group"

    ingress {
        from_port = 22
        to_port = 22
        protocol = "tcp"
        cidr_blocks = ["0.0.0.0/0"]
    }

    ingress {
        from_port = 4001
        to_port = 4001
        protocol = "tcp"
        cidr_blocks = ["0.0.0.0/0"]
    }

    ingress {
        from_port = 7001
        to_port = 7001
        protocol = "tcp"
        cidr_blocks = ["0.0.0.0/0"]
    }


    vpc_id = "${aws_vpc.default.id}"
}

  availability_zones = ["${aws_instance.nat.availability_zone}"]
  name = "coreos"
  max_size = 12
  min_size = 3
  health_check_grace_period = 300
  health_check_type = "ELB"
  desired_capacity = 3
  force_delete = true
  launch_configuration = "${aws_launch_configuration.coreos.id}"
}

    name = "coreos"
    image_id = "${lookup(var.aws_coreos_amis, var.region)}"
    instance_type = "m3.medium"
    key_name = "${var.aws_key_name}"
    security_groups = ["${aws_security_group.coreos.id}"]

    user_data = "#cloud-config\n\ncoreos:\n  etcd:\n    discovery: ${var.coreos_token}\n    addr: $private_ipv4:4001\n    peer-addr: $private_ipv4:7001\n  units:\n    - name: etcd.service\n      command: start\n    - name: fleet.service\n      command: start"
