Empty tags on root_block_device

[andormarkus]

Description

With V2.18.0 if I don't fill out the tags for the root_block_device then I will get the following error:

│ Error: Incorrect attribute value type
│ 
│   on .terraform/modules/ec2_this/main.tf line 38, in resource "aws_instance" "this":
│   38:       tags                  = lookup(root_block_device.value, "tags", null)
│ 
│ Inappropriate value for attribute "tags": map of string required.

My TF file looks like this:

module "ec2_this" {
  source  = "terraform-aws-modules/ec2-instance/aws"
  version = "2.18.0"

  name                        = "this"
  ami                         =  XXXXXXX
  instance_type               = "t3a.xlarge"
  monitoring                  = true
  vpc_security_group_ids      = XXXXXXX
  subnet_id                   = XXXXXXX

  root_block_device = [
    {
      volume_type = "gp2"
      volume_size = 100
    },
  ]
}

If I put there some placeholder tags I got this error:

│ Error: Invalid value for module argument
│ 
│   on ec2.tf line 109, in module "ec2_this":
│  109:   root_block_device = [

│  112:       volume_size = 100
│  113:       tags        = {
│  114:         Name = "fooo"
│  115:       }
│  116:     },
│  117:   ]
│
