cdktf: synth --hcl fails to render false(bool), 0(int), ""(empty string)

[tenminus11]

Expected Behavior

false should come as a parameter instead it is empty in hcl, it is present in .json
"" empty string in resource and module also fails to render
0 value also fails to render in module

module "prj_vpc-host-hub" {
  billing_account                = "${var.billing_id}"
  enable_shared_vpc_host_project = false
  folder_id                      = "${google_folder.fldr_Common.name}"
  name                           = "vpc-host-hub"
  org_id                         = "${var.organization_id}"
  source                         = "terraform-google-modules/project-factory/google"
  version                        = "~> 15.0"
}

Actual Behavior

module "prj_vpc-host-hub" {
  billing_account                = "${var.billing_id}"
  enable_shared_vpc_host_project =
  folder_id                      = "${google_folder.fldr_Common.name}"
  name                           = "vpc-host-hub"
  org_id                         = "${var.organization_id}"
  source                         = "terraform-google-modules/project-factory/google"
  version                        = "~> 15.0"
}

Steps to Reproduce

projects_arg = {
                "name": project,
                "org_id": organization_id.string_value,
                "billing_account": billing_id.string_value,
                "enable_shared_vpc_host_project": False,
                **proj_param,
            }
ProjectFactory(self, f"prj_{project}", **projects_arg)
