Terraform: Ошибка при обновлении формата файла состояния с версии 3 до версии 4 / переименование псевдонима соответствующего поставщика в допустимый идентификатор

Question

Я получил эту ошибку при обновлении файла состояния:

Error upgrading state file format from version 3 to version 4: invalid
provider config reference "provider.aws.${var.short_region}" for
aws_route53_zone.zone: this alias seems to contain a template interpolation
sequence, which was not supported but also not error-checked in Terraform
0.11. To proceed, rename the associated provider alias to a valid identifier
and apply the change with Terraform 0.11 before upgrading to Terraform 0.12.

Моя конфигурация: Terraform v0.12.20, поставщик. aws v2.55.0, provider.null v2.1.2, provider.template v2.1.2

Код изначально был в 0.11 версии и был обновлен до 0.12. Теперь код находится в 0.12

На моей машине файл состояния:

    },

В main.tf нет ничего похожего на "provider.aws.${var.short_region}".

В других 2 подмодулях есть только то, что:

module private-hosted-zone.tf
resource "aws_route53_zone" "zone" {
  name = var.subdomain
  vpc {
    vpc_id = var.vpc_id
  }
  comment = "Private Zone for ${var.environment_name}"

  tags = {
    Name            = "${var.environment_name}-r53-private"
    Environment     = var.environment_name
    EnvironmentType = var.environment_type
    FullRegion      = var.aws_region
    ShortRegion     = var.short_region
    Terraform       = "true"
  }
}

module public-hosted-zone.tf
resource "aws_route53_zone" "zone" {
  name    = var.subdomain
  comment = "Public Zone for ${var.environment_name}"

  tags = {
    Name            = "${var.environment_name}-r53-public"
    Environment     = var.environment_name
    EnvironmentType = var.environment_type
    FullRegion      = var.aws_region
    ShortRegion     = var.short_region
    Terraform       = "true"
  }
}

Не могу понять, как это исправить ...
