Attempting conversion containing for_each with primitives fails

[smithrobs]

What happened?

The pulumi convert --from terraform --language python command does not work for terraform for-loops that have primitives. For example for_each = var.enable ? [1] : [] which we typically do for dynamic blocks such as S3 lifecycle rules which has to be defined in a single resource (ref). The error message is:

error: main.pp:7,40-75: cannot traverse value of type number;
error: main.pp:7,40-75: cannot traverse value of type union(cty.NumberIntVal(1), none);
error: could not generate output program

Example

resource "aws_s3_bucket_lifecycle_configuration" "this" {
  count  = length(var.expirations) > 0 || length(var.transitions) > 0 || length(var.noncurrent_version_transitions) > 0 ? 1 : 0
  bucket = aws_s3_bucket.this.id
  
  # There are some other dynamic rule blocks i have omitted

  dynamic "rule" {
    for_each = var.transitions
    content {
      status = try(rule.value.enabled, true) ? "Enabled" : "Disabled"
      id     = try(rule.value.id, md5("transitions${jsonencode(rule.value)}"))
      dynamic "abort_incomplete_multipart_upload" {
        # following line will fail to convert
        for_each = try(rule.value.abort_incomplete_multipart_upload_days, null) != null ? [1] : []
        content {
          days_after_initiation = rule.value.abort_incomplete_multipart_upload_days
        }
      }
      filter {
        prefix = try(rule.value.prefix, "")
        dynamic "tag" {
          for_each = try(jsondecode(rule.value.tags), [])
          content {
            key   = try(tag.key, null)
            value = try(tag.value, null)
          }
        }
      }
      transition {
        date          = try(rule.value.date, null)
        days          = try(rule.value.days, null)
        storage_class = rule.value.storage_class
      }
    }
  }
}
