unable to modify volume type from gp2 to gp3 for ebs_volumes

[mwimpelberg28]

Description

Under the variable ebs_volumes_db01 which is utilized by ebs_block_device, I created an ebs volume called xvdb with type gp2. When I change the volume type to gp3, no change is reflected in tf for that device.

• [x] ✋ I have searched the open/closed issues and my issue is not listed.

Versions

• Module version [Required]: v4.3.0

• Terraform version: Terraform v1.4.1 on darwin_amd64

• Provider version(s): provider registry.terraform.io/hashicorp/aws v4.58.0

Reproduction Code [Required]

variable "ebs_volumes_db01" {
  default = [
    {
      device_name = "xvdb"
      volume_type = "gp3"
      volume_size = 10
      encrypted   = true
    }
  ]
}

variable "ebs_optimized_db01" {
  default = false
}

variable "root_block_device" {
  default = [
    {
      volume_type = "gp3"
      volume_size = 150
      encrypted   = true
    }
  ]
}

module "ec2-db01" {
  source  = "github.com/terraform-aws-modules/terraform-aws-ec2-instance.git?ref=v4.3.0"
  name                        = "test-instance"
  ami                         = "ami-0d1feff6b88eb18bd"
  instance_type               = "t3.medium"
  subnet_id                   = "subnet-01b149f7dbd1588cc"
  vpc_security_group_ids      = ["sg-027b3e41152846307"]
  associate_public_ip_address = false
  key_name                    = "test-keypair"
  monitoring                  = false
  root_block_device = var.root_block_device
  ebs_block_device = var.ebs_volumes_db01
}

Steps to reproduce the behavior:

No

Yes

I changed the variable from gp2 to gp3

Expected behavior

I expect the volume type to change for all volumes.

Actual behavior

Only the root volume showed a change

  # module.ec2-db01.aws_instance.this[0] will be updated in-place
  ~ resource "aws_instance" "this" {
        id                                   = "i-041828532d8825372"
        tags                                 = {
            "Name" = "test-instance"
        }
        # (31 unchanged attributes hidden)

      ~ root_block_device {
            tags                  = {}
          ~ volume_type           = "gp2" -> "gp3"
            # (8 unchanged attributes hidden)
        }

        # (8 unchanged blocks hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.
