Error:

Error: updating Auto Scaling Group (xyz): ValidationError: You must use a valid fully-formed launch template. Value (arn:aws:iam::012345678901:instance-profile/node-xyz) for parameter iamInstanceProfile.arn is invalid. Invalid IAM Instance Profile ARN

Terraform CLI and Terraform AWS Provider Version

Terraform version: 0.12.23
Terraform AWS Provider Version: v2.70.0

Affected Resource(s)

aws_iam_instance_profile
aws_launch_template
aws_autoscaling_group

Repeat of an earlier reported issue

Similar Terraform configuration, behavior and error as reported in #5217

The issue was fixed in 1.34.0 (#5633)

Could we consider bumping the propagation timeout to mitigate this further? https://github.com/hashicorp/terraform-provider-aws/blob/main/internal/service/autoscaling/consts.go#L10

Hey @riddhi89 👋 Thank you for taking the time to raise this! I noticed you mentioned you're using AWS Provider version 2.70.0. In that version of the provider, the timeout was still 1 * time.Minute, however, in subsequent versions, it uses 2 * time.Minute, as seen in the link you provided to the propagationTimeout constant. This change happened in AWS Provider version 3.35.0 with #17811. Can you upgrade to a later version that has this change and see if that improves the behavior?

This is still an issue (or has regressed) in v4.56.0.

I'm seeing the error below when changing the instance profile for an ASG via a launch template.

This is still an issue in 5.1.0:

updating Auto Scaling Group (hub-asg-example): ValidationError: You must use a valid fully-formed launch template. Value (arn:aws:iam::0000000000:instance-profile/instance_hub-asg-example) for parameter iamInstanceProfile.arn is invalid. Invalid IAM Instance Profile ARN

Reproducer that doesn't work:

data "aws_iam_policy_document" "assume" {
    statement {
        actions = [ "sts:AssumeRole" ]
        principals {
            type = "Service"
            identifiers = [ "ec2.amazonaws.com" ]
        }
    }
}

resource "aws_iam_role" "this" {
    name = "my-role"
    assume_role_policy = data.aws_iam_policy_document.assume.json
}

resource "aws_iam_instance_profile" "this" {
    name = "my-instance-profile"
    role = aws_iam_role.this.name
}

resource "aws_launch_template" "this" {
    name = "my-launch-template"
    image_id = "ami-0ff8a91507f77f867"
    instance_type = "t2.micro"
    iam_instance_profile { name = aws_iam_instance_profile.this.name }
}

resource "aws_autoscaling_group" "this" {
    name = "my-autoscaling-group"
    min_size = 1
    max_size = 1
    desired_capacity = 1
    launch_template { id = aws_launch_template.this.id }
    vpc_zone_identifier = [ "subnet-12345678" ]
}

The equivalent Amazon CDK works fine and is able to create the auto scaling group fine and attach the instance profile:

    const vpc = new ec2.Vpc(this, "Vpc")
    new autoscaling.AutoScalingGroup(this, "AutoScalingGroup", {
      vpc,
      launchTemplate: new ec2.LaunchTemplate(this, "LaunchTemplate", {
        machineImage: new ec2.AmazonLinuxImage(),
        instanceType: new ec2.InstanceType("t2.micro"),
        instanceProfile: new iam.InstanceProfile(this, "InstanceProfile"),
      }),
    })
