I tried out the creation of EC2 Instances using aws_launch_template{} and aws_instance{} resources , but after doing that, the detailed monitoring does not activate and for some reason I get such result:

My launch template and EC2 Instance resource look like this:

resource "aws_launch_template" "name_lauch_template" {
  name = "main-launch-template"
  image_id = "ami-0314c062c813a4aa0"
  update_default_version = true
  instance_type = "t3.medium"
  ebs_optimized = false
  key_name = aws_key_pair.main.key_name

  monitoring {
    enabled = true
  }

  hibernation_options {
    configured = false
  }

  network_interfaces {
    associate_public_ip_address = true
    security_groups = [ "${aws_security_group.main_sg.id}" ]
  }
}

resource "aws_instance" "main_instances" {
  count = 5
  availability_zone = "eu-west-3a"

  launch_template {
    id = aws_launch_template.name_lauch_template.id
  }
}

I have monitoring{} block defined and have monitoring enabled so why is it writing that it is disabled ? Has anyone else encountered this problem and know the solution ?
