Use collection variable value from K6 setup in the K6 default

[dparadisZentelia]

I try to do a K6 script base on my Postman collection, where I have a part with a setup to get the token.
After I want to loop a specific request ("create User") that required the colSpecialId created in the setup.
I use Postman-to-k6 (BTW amazing tool) to convert my collection in K6 script.
After I move the setup folder in the K6 setup function like this:

// Auto-generated by the postman-to-k6 converter

import "./libs/shim/core.js";
import { group } from "k6";
import "./requests/setup/get-client-bearer-token.js";
import "./requests/setup/create-HealthcareService.js";
import "./requests/setup/create-Schedule.js";
import "./requests/loop/create-Slot.js";

export let options = { maxRedirects: 4 };

const Request = Symbol.for("request");
postman[Symbol.for("initial")]({
  options,
  collection: {
    colClientToken: "",
    colSpecialId: ""
  },
  environment: {
    envBaseUrl: "http://localhost:8080"
  }
});

export function setup() {
  group("setup", function() {
    postman[Request]("get client bearer token");
    postman[Request]("get special ID");
  });
}

export default function() {
  group("loop", function() {
    postman[Request]("create User");
  });
}

test part in the "get special ID"

  post(response) {
    const jsonResponse = pm.response.json();
    let id = jsonResponse.id;
    pm.collectionVariables.set("colSpecialId", id);
   console.log("colSpecialId: " + id);
  }

the body in the "create User"
data:
'{\n "schedule": {"id": "{{colSpecialId}}"}, "name": "joe"}',
auth(config, Var) {
config.headers.Authorization = Bearer ${pm[Var]("colClientToken")};
}

The value of colSpecialId is empty, on the call made, but I could see the console log "colSpecialId: 1234"
and the colClientToken is resolved.

Any idea to workaround the problem to resolve {{colSpecialId}} ?

I found a workaround, not very clean, but that solve my problem to communicate from setup to default.

export function setup() {
  let call="";
  group("setup", function() {
    postman[Request]("get client bearer token");
    call = postman[Request]("get special ID");
   //call contain a copy of the request definition where I set colSpecialId in the header Specialid
  });
  //use the return to persist the colSpecialId to the default function
  return call.request.headers;  
}


export default function(data) {
  group("loop", function() {
    postman[Pre].push(() => {
      //read from data the header Specialid I set in the setup
      pm.collectionVariables.set("colSpecialId", data.Specialid);
    });
