Terraform Version & Provider Version(s)

Terraform v0.12.31
on Jenkins
provider registry.terraform.io/hashicorp/.google v6.22.0
provider registry.terraform.io/hashicorp/external v2.3.4

Affected Resource(s)

google_bigtable_table

Terraform Configuration

resource "google_bigtable_table" "table" {
  for_each            = var.bigtable_name
  name                  = each.value.name
  instance_name = google_bigtable_instance.instance.name
  split_keys          = each.value.split_keys
  project               = var.project

  column_family {
    family = each.value.column_family
  }

  automated_backup_policy {
    retention_period = var.retention_period
    frequency            = var.frequency
  }

  depends_on = [
    google_bigtable_instance.instance,
  ]
}

We have set the vars to:

variable "retention_period" {
  description = "The retention period of the bigtable table backups value in string"
  type        = string
  default     = "0h0m0s"
}


variable "frequency" {
  description = "The frequency in which you want the backups"
  type        = string
  default     = "0h0m0s"
}

and have also tried the following for completion:

variable "retention_period" {
  description = "The retention period of the bigtable table backups value in string"
  type        = string
  default     = "0"
}


variable "frequency" {
  description = "The frequency in which you want the backups"
  type        = string
  default     = "0"
}

Debug Output

No response

Expected Behavior

Terraform should have created a table with no backup as per the following documentation:

https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/bigtable_table#automated_backup_policy-1

automated_backup_policy Defines an automated backup policy for a table, specified by Retention Period and Frequency. To disable, set both Retention Period and Frequency to 0.

Actual Behavior

When creating an automated backup policy via terraform using the module google_bigtable_table we are seeing the following error:

Error: Error creating table. rpc error: code = InvalidArgument desc = Automated backup policy has an input retention period 0, which is out of the desired range of [72h, 2160h].

Google documentation states the following:

Which we assume this is why the error tells us between 72 hours and 2160 hours. This is not clarified in Terraform documentation. We imagine that 0 is not actually allowed due to the restriction described in the screenshot above.
