Provider functions are not supported?

Consider

test.tf

variable "lastname" {
  type = string
 default = "bär"
}

variable "firstname" {
  type    = string
  default = "föo"
}

terraform {
  required_providers {
    corefunc = {
      source  = "northwood-labs/corefunc"
      version = "1.5.1"
    }
  }
}

locals {
  username = provider::corefunc::str_iterative_replace(
    lower("${var.firstname}.${var.lastname}"),
    [
      { old = "ä", new = "ae" },
      { old = "ö", new = "oe" },
      { old = "ü", new = "ue" },
      { old = "ß", new = "ss" },
    ],
  )
}

output "out" {
  value = local.username
}

parse-hcl.js

const { parse } = require('@cdktf/hcl2json');
const fs = require('fs').promises;

const hclFilePath = 'test.tf';

(async () => {
  try {
    // Read the HCL content from the file
    const hcl = await fs.readFile(hclFilePath, 'utf-8');

    // Parse the HCL content
    const json = await parse(hclFilePath, hcl);

    // Output the parsed JSON
    console.log(JSON.stringify(json, null, 2));
  } catch (err) {
    console.error('Error:', err.message);
  }
})();

docker run -it --rm -v $PWD:/tmp -w /tmp --entrypoint bash node:20.17 -c "npm install @cdktf/hcl2json; node parse-hcl.js"

Error: parse config: [test.tf:22,22-23: Missing newline after argument; An argument definition must end with a newline.]

However, a terraform plan works fine. And the usage of provider::corefunc::str_iterative_replace is as describe here.

docker run -it --rm -v $PWD:/tmp -w /tmp hashicorp/terraform:1.10 init 
docker run -it --rm -v $PWD:/tmp -w /tmp hashicorp/terraform:1.10 plan 

Changes to Outputs:
  + out = "foeo.baer"

You can apply this plan to save these new output values to the Terraform state, without changing any real infrastructure.

I think this should be fixed in v0.6.5
