lookup default value for soft delete policy results in Error

TL;DR

On a multi-bucket configuration, adding a soft_delete_policy configuration block like so:

soft_delete_policy = { "bucket1" = { // Disable protection on this bucket retention_duration_seconds = 0 } "bucket2" = { // Increase protection to the max value (90 days) retention_duration_seconds = 7776000 } } ; results in the following error:

│ Error: Invalid function argument │ │ on .terraform/modules/gcs.cloud_storage/main.tf line 160, in resource "google_storage_bucket" "buckets": │ 160: for_each = [lookup(var.soft_delete_policy, each.value, {})] │ ├──────────────── │ │ while calling lookup(inputMap, key, default...) │ │ Invalid value for "default" parameter: the default value must have the same │ type as the map elements.

Expected behavior

The module should allow to create a soft_delete block for a multibucket configuration without issues.

There is a PR opened to solve this https://github.com/terraform-google-modules/terraform-google-cloud-storage/pull/318

Observed behavior

The buckets should have the correct soft_delete retention time when deployed
