terraform ecs/CreateCapacityProvider request 500

Question

I am getting the following error while trying to create an ECS cluster, at the capacity provider creation phase.

no details about the error, any idea what might be wrong here?

here is a snippet from my terraform for capacity provider:

... (other stuff like ASG launch template etc)

resource "aws_autoscaling_group" "cluster-asg" {
  desired_capacity = 3
  min_size = 3
  max_size = 50
  availability_zones = ["us-east-1a", "us-east-1b", "us-east-1c"]

  launch_template { 
    id = aws_launch_template.as_launch_template.id
    version = "$Latest"
  }

  tag {
    key                 = "AmazonECSManaged"
    value               = true
    propagate_at_launch = true
  }
}


resource "aws_ecs_capacity_provider" "capacity_provider" {
  name = "app-client-capacity-provider"

  auto_scaling_group_provider {
    auto_scaling_group_arn         = aws_autoscaling_group.cluster-asg.arn

    managed_scaling {
      instance_warmup_period    = 120
      maximum_scaling_step_size = 1000
      minimum_scaling_step_size = 1
      status                    = "ENABLED"
      target_capacity           = 80
    }
  }
}

resource "aws_ecs_cluster" "cluster" {
  name = "app-client" # Naming the cluster
  capacity_providers = [aws_ecs_capacity_provider.capacity_provider.name]
}

Answer 1

I fixed this by creating the cluster without capacity provider first then modifying it to have one.
