variable "name_prefix" {
  type = "string"
  default = "NO_PREFIX_SET"
}

variable "policy_arn" {
  type = "string"
  default = "NO_POLICY_ARN_SET"
}

data "aws_iam_policy_document" "ec2_assume_role_policy" {
  statement {
    effect = "Allow"
    principals {
      type = "Service"

Debug Output

Please provider a link to a GitHub Gist containing the complete debug output: https://www.terraform.io/docs/internals/debugging.html. Please do NOT paste the debug output in the issue; just paste a link to the Gist.

Expected Behavior

What should have happened?

The instance_profile_uid output should have the unique id for the instance profile.

Actual Behavior

What actually happened?

There is no unique_id defined for the instance profile. Even the state does not include a unique_id attribute:

 tf state show <redacted>.aws_iam_instance_profile.ec2_profile               
id               = <redacted>_ec2_instance_profile
arn              = arn:aws:iam::<redacted>:instance-profile/<redacted>_ec2_instance_profile
name             = <redacted>_ec2_instance_profile
path             = /
roles.#          = 1
roles.4291128237 = <redacted>_ec2_role

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform plan -out myplan
2. terraform apply myplan
