[BUG]: imported github_repository_custom_property type missing

[imaspen]

Expected Behavior

On importing a repository custom property, it should include the type, and the resource should not be replaced where the resource configuration is correct.

Actual Behavior

The property_type is set to null, which causes the configuration to trigger a forced replacement of the resource.

Terraform Version

Terraform v1.10.4
on darwin_arm64

• provider registry.terraform.io/integrations/github v6.6.0

Affected Resource(s)

• github_repository_custom_property

Terraform Configuration Files

resource "github_repository_custom_property" "test" {
  repository     = "test_repo"
  property_name  = "test_property"
  property_type  = "string"
  property_value = ["test_value"]
}

import {
  to = github_repository_custom_property.test
  id = "test_org:test_repo:test_property"
}

Steps to Reproduce

Import an existing custom property with the config like the above, it will force recreation due to the difference in types.

Debug Output

# Warning: this will destroy the imported resource
-/+ resource "github_repository_custom_property" "project" {
      ~ id             = "REDACTED" -> (known after apply)
        property_name  = "Project"
      + property_type  = "string" # forces replacement
        property_value = [
            "REDACTED",
        ]
        repository     = "REDACTED"
    }
