Terraform CLI and Terraform AWS Provider Version

Affected Resource(s)

• aws_instance

Expected Behavior

terraform apply should work as usual

Actual Behavior

  on ../../../modules/instance/main.tf line 61:
  61: resource "aws_instance" "instance_no_ebs" {

Instance
module.nomad_servers.module.nomad_server_instances.module.instance.aws_instance.instance_no_ebs[1]
data could not be decoded from the state: unsupported attribute
"network_interface_id".

Steps to Reproduce

1. terraform init to download latest provider version (3.0.0)
2. terraform apply

Important Factoids

• error is not presented during plan, only apply
• reverting to version 2.70.0 of the provider fixes the issue,

[emulanob]

Most definitely caused by 3586a1a#diff-28aade55afa0cda57279a9d35d523488.

The error had already been bypassed on plan because the attribute is used in an output which I wrapped in a try() function, Therefore it could be planned successfully but not applied, when terraform tries to retrieve the attribute from the state.

We see a very similar problem, that actually breaks in the plan stage. This affects placement_strategy for ECS service which is now I believe ordered_placement_strategy. We probably could bypass by destroying and redeploying the infra but it would be nice to not have to.

terraform validate
Success! The configuration is valid.

terraform plan
Error: Invalid resource instance data in state

  on .terraform/modules/ecs_app/ecs_service/main.tf line 28:
  28: resource "aws_ecs_service" "service" {

Instance module.ecs_app.aws_ecs_service.service data could not
be decoded from the state: unsupported attribute "placement_strategy".

make: *** [plan] Error 1

Hi folks 👋 Thank you for reporting this issue and apologies for the frustrating behavior. Something is certainly amiss with the physical removal of the attributes from the provider schema, but usually Terraform core handles these just fine.

It would be very helpful if you all could provide the following information, so we can start troubleshooting this:

• Terraform CLI version
• Steps (e.g. commands ran, including upgrading the Terraform AWS Provider) that led to this error
• Snippet of Terraform configuration associated with the resource reporting the error
• A Gist with trace logging enabled so we can further troubleshoot. If you are worried about any sensitive data, it can be encrypted with the HashiCorp GPG Key or redacted as necessary.

Hopefully with those outlined, we can figure out root cause. Relevant Terraform core logic triggering the error.

• TF CLI 0.12.29, using the hashicorp/terraform:light image in docker hub
• terraform validate or terraform apply
• Having an output is what led to this error for me:

output "network_interface_id" {
  description = "ID of the network interface that was created with the instance."
  value       = aws_instance.<module_name>.network_interface_id
}

[emulanob]

In my case it's also because of an output.

I have more info in #14458 but noting here for compactness. In my case plan fails because my existing state was generated with 2.70.0 and has removed attributes listed:

    {
      "module": "module.my-module",
      "mode": "data",
      "type": "aws_region",
      "name": "main",
      "provider": "provider[\"registry.terraform.io/hashicorp/aws\"].my-module",
      "instances": [
        {
          "schema_version": 0,
          "attributes": {
            "current": null,
            "description": "US East (N. Virginia)",
            "endpoint": "ec2.us-east-1.amazonaws.com",
            "id": "us-east-1",
            "name": "us-east-1"
          }
        }
      ]
    },

current was removed from the aws_region datasource in 3.0.0

Issue is happening to me as well when going from aws provider version 2.70.0 to 3.0.0

• Version: Terraform v0.13.0-rc1, provider registry.terraform.io/hashicorp/aws v3.0.0
• Action: terraform apply or terraform destroy
• Resource:

resource aws_route53_zone external {
  name = var.domain-name
  comment = "${var.environment}-external-zone"

  tags = {
    Environment = var.environment
  }
}

• Error: ...data could not be decoded from the state: unsupported attribute "vpc_id"

Edit:
Also seeing the same issue with the following:
data aws_availability_zones available {}
Error: ...data could not be decoded from the state: unsupported attribute "blacklisted_names".

And:
data aws_iam_role iam_for_lambda {
Error: ...data could not be decoded from the state: unsupported attribute "assume_role_policy_document".

Please note that I have filed a bug report upstream with Terraform core, where this error is being generated: hashicorp/terraform#25752

Just updated to v0.13 and the terraform **plan** fails.

Terraform v0.13.0

• provider registry.terraform.io/-/aws v3.1.0
• provider registry.terraform.io/hashicorp/aws v3.1.0

Commands used:

terraform 0.13update (added new required_providers)
terraform init
terraform plan

Failure (multiple times for the same aws_instance resource):

Error: Invalid resource instance data in state

  on main.tf line 313:
 313: resource "aws_instance" "instance" {

Instance aws_instance.instance data could not be decoded from the state:

  vpc_security_group_ids = [
    aws_security_group.ssh.id,
    aws_security_group.http.id,

  key_name = var.use_existingKey ? var.fixed_key_name : aws_key_pair.auth[0].id

  volume_tags = {

  }

  tags = {
    Name = format("%s-ws_%s-ami_%s", var.basename, terraform.workspace, var.ami_name)
  }
}

Hi folks 👋 A fix for this particular Terraform state handling issue was merged upstream in the Terraform CLI code and will release with Terraform CLI version 0.13.1 in the coming days.

If you happen to have a reproducible case of this issue with only Terraform CLI 0.12.x, please create a new bug report issue in the hashicorp/terraform repository with all the template details and the teams will triage further. Thanks.

[andresvia]

Is there a workaround meanwhile?

@andresvia alas, you have to manually edit the state file to exclude the deprecated attributes for now, I think. That worked for us at least.
