github_actions_environment_variable: 409 Variable already exists

[voltagex]

Given the following Terraform

terraform {
  required_providers {
    github = { source = "integrations/github" }
  }
}

variable "my_repo_variables" {
  type = map(string)
  default = {
    "first_variable"  = "somevalue"
    "second_variable" = "someothervalue"
  }
}

variable "my_repo" {
  default = "github-terraform-example"
}

resource "github_repository_environment" "my_environment" {
  repository  = var.my_repo
  environment = "my_environment"
}

resource "github_actions_environment_variable" "mine" {
  for_each      = var.my_repo_variables
  repository    = var.my_repo
  variable_name = each.key
  value         = each.value
  environment   = github_repository_environment.my_environment.environment
}

The environment and variables are created successfully.

However, if I go and add THIRD_VARIABLE to my environment in the UI, then update the file accordingly, when I run terraform apply I get:

github_actions_environment_variable.mine["third_variable"]: Creating...
╷
│ Error: POST https://api.github.com/repos/voltagex/github-terraform-example/environments/my_environment/variables: 409 Already exists - Variable already exists []

│   on main.tf line 25, in resource "github_actions_environment_variable" "mine":
│   25: resource "github_actions_environment_variable" "mine" {

Shouldn't the provider notice that the state has changed outside of Terraform and try an update instead of failing immediately on a create?

Terraform import is not really an option for me as this is a minimal example of a problem I'm experiencing where the state is on a remote backend I don't have direct access to

Same issue. Even worse: my variable was originally created with terraform 🤷
