cdktf: hcl render failing resource(""); locals, variable in false(bool), 0(int), ""(str) value

[tenminus11]

resource with "" empty string does not render in hcl
variable default value 0,false,"" does not render in hcl
local with value 0,false,"" does not render in hcl

Expected Behavior

locals {
  local_bool: false,
  local_num: 0,
  local_str: ""
}

variable "var_str" {
  type = string
  default: "",
}

variable "var_bool" {
  type = bool
  default: false,
}

variable "var_num" {
  type = number
  default: 0,
}
resource "google_compute_network" "nw_vpc" {
  auto_create_subnetworks = false
  description             = ""
  mtu                     = 0
  name                    = "vpc-network"
}

Actual Behavior

locals {

}

variable "var_str" {
  type = string
}

variable "var_bool" {
  type = bool
}

variable "var_num" {
  type = number
}
resource "google_compute_network" "nw_vpc" {
  auto_create_subnetworks = false
  description             =
  mtu                     = 0
  name                    = "vpc-network"
}

Steps to Reproduce

        TerraformVariable(
            self,
            "var_str",
            default="",
            type="string",
        )
        TerraformVariable(
            self,
            "var_bool",
            default=False,
            type="bool",
        )
        TerraformVariable(
            self,
            "var_num",
            default=0,
            type="number",
        )
        TerraformLocal(
            self,
            "local_str",
            ""
        )
        TerraformLocal(
            self,
            "local_num",
            0
        )
        TerraformLocal(
            self,
            "local_bool",
            False
        )
        ComputeNetwork(
            self,
            "nw_vpc",
            name="vpc-network",
            description="",
            auto_create_subnetworks=False,
            mtu=0
        )
