  }

Debug Output

Panic Output

Expected Behavior

number of schedulers in environment is updated

Actual Behavior

number of schedulers in environment was not updated

Steps to Reproduce

starting config:

provider "google" {
  region = "us-central1"
  project = "my-project"
}

resource "google_composer_environment" "testman" {
  name   = "sample-name"
  region = "us-central1"
  project = "my-project"

  config {
    software_config {
      image_version = "composer-1.19.0-airflow-2.2.5"
    }

    private_environment_config {
      enable_private_endpoint = true
    }

    node_config {
      ip_allocation_policy {
        use_ip_aliases = true
      }
    }
  }
}

1. terraform apply
2. environment is created properly
3. changing configuration (scheduler_count -> 2)

provider "google" {
  region = "us-central1"
  project = "my-project"
}

resource "google_composer_environment" "testman" {
  name   = "sample-name"
  region = "us-central1"
  project = "my-project"

  config {
    software_config {
      image_version = "composer-1.19.0-airflow-2.2.5"
      scheduler_count = 2
    }

    private_environment_config {
      enable_private_endpoint = true
    }

    node_config {
      ip_allocation_policy {
        use_ip_aliases = true
      }
    }
  }
}

4. terraform apply
5. environment still has one scheduler
