UPDATED - Terraform OCI - create multiple VCN in different regions

I would like to create 2 VCN and other resources inside two or more regions.

I upload my code inside this github account

When i execute the code (you have to set the tenancy, user, fingerprint, etc) i don't have errors, but:

1. When I go to the root region, all is created (compartment and VCN)
2. when I go to the second region, the VCN is not created

terraform version: v1.0.2

my VCN module has:

terraform {
  required_providers {
    oci = {
      source = "hashicorp/oci"
      version = ">= 1.0.2"
      configuration_aliases = [
        oci.root,
        oci.region1
      ]
    }
  }
}

And when i call the VCN module I pass:

module "vcn" {
  source            = "./modules/vcn"
  
  providers = {
    oci.root = oci.home
    oci.region1 = oci.region1
  }
...
...

And my providers are:

provider "oci" {
  alias             = "home"
  tenancy_ocid      = local.json_data.TERRAFORM_work.tenancy_ocid
  user_ocid         = local.json_data.TERRAFORM_work.user_ocid
  private_key_path  = local.json_data.TERRAFORM_work.private_key_path
  fingerprint       = local.json_data.TERRAFORM_work.fingerprint
  region            = local.json_data.TERRAFORM_work.region
}

provider "oci" {
  alias             = "region1"
  region            = var.region1
  tenancy_ocid      = local.json_data.TERRAFORM_work.tenancy_ocid
  user_ocid         = local.json_data.TERRAFORM_work.user_ocid
  private_key_path  = local.json_data.TERRAFORM_work.private_key_path
  fingerprint       = local.json_data.TERRAFORM_work.fingerprint
}

What should i change, to create this VCN inside the two regions or more, at the same time?

using the terraform plan and apply

Thanks so much

Your module module.vcn does not declare any provider. From docs:

each module must declare its own provider requirements,

So you have to add to your module something like:

terraform {
  required_providers {
    oci = {
      source  = "source_for-oci"
      version = ">= your_version"
    }
  }
}
