Affected Resource(s)

google_firestore_field

Terraform Configuration

resource "google_firestore_field" "BatchOperation_expiresAt" {
      project    = "my-project-id"
      database   = "(default)"
      collection = "BatchOperation"
      field      = "expiresAt"
      ttl_config {}
}

Debug Output

No response

Expected Behavior

After importing the existing TTL using terraform import 'google_firestore_field.BatchOperation_expiresAt' 'projects/my-project-id/databases/(default)/collectionGroups/BatchOperation/fields/expiresAt, I would have expected no changes when doing a terraform plan.

Actual Behavior

Terraform said it was going to apply the following change:

# google_firestore_field.BatchOperation_expiresAt will be updated in-place
~ resource "google_firestore_field" "BatchOperation_expiresAt" {
    + field      = "expiresAt"

Steps to reproduce

1. Use cloud console to create a TTL policy on a Firestore in Datastore model
2. Import it using terraform import 'google_firestore_field.BatchOperation_expiresAt' 'projects/my-project-id/databases/(default)/collectionGroups/BatchOperation/fields/expiresAt
3. Run terraform plan

Important Factoids

This is the output of terraform state show:

> terraform state show google_firestore_field.BatchOperation_expiresAt
# google_firestore_field.BatchOperation_expiresAt:
resource "google_firestore_field" "BatchOperation_expiresAt" {
    collection = "BatchOperation"
    database   = "(default)"
    id         = "projects/my-project-id/databases/(default)/collectionGroups/BatchOperation/fields/expiresAt"
    name       = "projects/my-project-id/databases/(default)/collectionGroups/BatchOperation/fields/expiresAt"
    project    = "my-project-id"

    timeouts {}

    ttl_config {
        state = "ACTIVE"
    }

}

The field seems to be missing from the config.

Confirmed issue during the plan. It appears that immediately after import, the Terraform state has a null field, which is incorrect. There is likely some issue with the custom import code (it actually looks like there is a custom import defined for this resource, but it is not being used).
