Unsupported argument "target_object_key_format" in resource aws_s3_bucket_logging despite using aws-provider v5.31

Hi all, I’m trying to use the relatively new partitioned prefix functionality for server access logging described in Terraform Registry, however I’m getting the following error:

Error: Unsupported argument
│
│ on main.tf line 209, in resource "aws_s3_bucket_logging" "example":
│ 209: target_object_key_format = {
│
│ An argument named "target_object_key_format" is not expected here. Did you

2024-01-18T19:47:47.138Z [DEBUG] provider: plugin exited

My resource configuration is as follows:

resource "aws_s3_bucket_logging" "example" {
  bucket = "bucket-1"

  target_bucket = "bucket-2"
  target_prefix = "log/"

  target_object_key_format = {
    partitioned_prefix = {
      partition_date_source = "DeliveryTime"
    }
  }
}

Has anyone seen this / knows a workaround?
