ISSUE TYPE

• Bug Report

COMPONENT NAME

ecs_service.py

ANSIBLE VERSION

v2.10.1

OS / ENVIRONMENT

Docker inside alpine image.

STEPS TO REPRODUCE

Just execute the following task and it should fail.

- name: "Criando/atualizando serviço {{ service.name }}" 
  community.aws.ecs_service:
    aws_access_key: "{{ ec2_access_key }}"
    aws_secret_key: "{{ ec2_secret_key }}"
    state: present
    force_new_deployment: yes
    name: "{{ service.name }}"
    cluster: "{{ service.cluster }}"
    region: "{{ service.region }}"
    task_definition: "{{ service.task }}"
    desired_count: 1 #service.desired_count
    launch_type: "{{ service.launch_type }}"
    load_balancers:
      - targetGroupArn: "{{ service.alb_arn_tg }}"
        containerName: "{{ service.http_container }}"
        containerPort: 80 
    network_configuration:
      subnets:
      - "{{ service.subnet  }}"
      security_groups:
      - "{{ service.security_group }}"

My var file is here, in case you're wondering:

  name: "Service_Site_Plataforma"
  cluster: "openbox-plataforma"
  region: "us-east-1"
  task: "openbox-plataforma-prod:11"
  desired_count: 1
  launch_type: "FARGATE"
  alb_arn_tg: "arn:aws:elasticloadbalancing:us-east-1:880610698981:targetgroup/ECS-site/5f7722edab69f6a3"
  http_container: "nginx-server"
  http_container_port: 80
  vpc: "vpc-0813fd6181f0580a4" 
  subnet: "subnet-051274368a7c79e66"
  security_group: "sg-08e8273b3b2959ada"

EXPECTED RESULTS

It should work.

ACTUAL RESULTS

It fails with the following error message:

somewhere is a type error

TypeError: string indices must be integers

So somehwere you're refering to a position of an array? But I cannot find it adhoc.
Basically we do the same all day...

#264

same error. element type is wrong for load _balancers.

@Lennon95 as a workaround, you can use community.aws collection 1.0.0. The error was introduced later.
