Terraform Configuration Files

resource "aws_ecs_task_definition" "service" {
  family = "test"
  container_definitions = jsonencode([
    {
      name      = "test"
      image     = "service-first"
      cpu       = 10
      memory    = 512
      essential = true
      portMappings = [
        {
          containerPort = 80
          hostPort      = 80
        }
      ]
    }
  ])
}

Steps to Reproduce

1. create a new task def via terraform
2. in the aws console unregister it
3. change the drop down to display unregistered tasks and choose to delete the task
4. change the drop down to display delete in progress tasks and wait 30-60+ minutes
5. once the task disappears from delete in progress run terraform plan

I'm getting the same error since morning. I did exactly whats mentioned in steps to reproduce section. And now because of this error our whole staging environment is effected.

[caseyoneill]

I am seeing the same issue with Terraform 1.4.0 and AWS 4.58.0. The task definitions were manually deleted outside of terraform. The only way to get things working again was to manually delete the task definitions from my Terraform state file by running:

terraform state rm <module>.aws_ecs_task_definition.aws-ecs-task

[bploetz]

Ran into this too (we recently started deleting old task defs as part of our release process) and @caseyoneill 's suggestion fixes the problem (you obviously need to recreate the resource you delete from the state file).

Hi, everyone! I see the issue and understand the suggestion by @caseyoneill, but sadly I get an error while removing that: Error saving the state: unsupported attribute "arn_without_revision" It's weird because I am not using that attribute anywhere in the code... Any idea?

[bhargavpanth]

Seem to be running into this issue. In my case, I am running tests (using Terratests to spin up ECS on Localstack). The only way to get around this issue seems to be by removing the task definition from the state. I am using Terraform v1.4.4 on darwin_arm64`. Is this a case of an un-updated Terraform version?

[david-hodgson-at-sky]

Also hit this issue following on from having having an issue with partially deleted task definitions (an AWS "feature" - state goes to DELETE_IN_PROGRESS and it's not deleted).

[DorisEckel8412]

Hi, we run in the same error message, after deleting 1 version of the task definition outside of terraform. We use version 1.7.3.

[justintilson-steeltoad]

I'm getting the same error with

Terraform: 1.7.4 cdktf: 0.20.3 @cdktf/provider-aws: 19.6.0

I'm completely blocked. I can't destroy or create resources in my workspace now.

I'm using Terraform Cloud.

I am getting same error with aws provider 5.16.2
