Terraform migration from v0.11 to v0.12 problem with tags

I'm trying migrate my terraform plan from v0.11 to v0.12 terraform version and when I execute the validation I have some error with the same error : "Unsupported block type" and the service mark the trouble into the "TAGS" tag with that comment:

Blocks of type "tags" are not expected here. Did you mean to define argument "tags"? If so, use the equals sign to assign it a value.

One example it's this troubling resource:

resource "aws_vpc" "VPC" {
  cidr_block           = "10.0.0.0/24"
  enable_dns_hostnames = "true"
  enable_dns_support   = "true"

  tags {
    Name        = "${var.name}-VPC-Default"
    Environment = var.env
    Region      = var.region
  }
}

I read into the documentation about this resource that support tag type "TAGS" and into the v0.11 version it's working fine.

Any suggestion about what it's my problem?

The error is explaining that in Terraform 0.12 tags are no longer a block, but rather now an argument. A block in Terraform appears like:

block { ... }

which is how your tags currently appear. An argument appears like:

argument = value

Therefore, you need to convert your tags from a block to an argument. That can be done like the following:

tags = {
  Name        = "${var.name}-VPC-Default"
  Environment = var.env
  Region      = var.region
}

where tags is now being assigned the map value you formerly contained within your block.
