Jest error TLSWRAP - not runnig with axios in Node.js

(Junior dev here :) )

Hi!! i m having problems running endpoints test with Jest. Just to let you be aware the endpoint i 'll show you is working because i test it manually with a http file.

node version = v18.8

My models in package.json(for the versions):

  "scripts": {
  "test": "jest --detect-open-handles"
  },
"devDependencies": {
    "@types/jest": "^29.0.0",
    "eslint": "^8.21.0",
    "eslint-config-prettier": "^8.5.0",
    "eslint-plugin-jest": "^27.0.1",
    "jest": "^29.0.1",
    "prettier": "^2.7.1"

the endpoint (a register):

router.post("/register", validator.authentificationValidation, hashPseudo,async (req, res, next) => {

let salt = bcrypt.genSaltSync(10);

let user = req.body;

if (user.pseudo == null || user.password == null) {
  res.status(400).json({
    error: "Missing fields",
  });
  return;
}

try {
  user.password = bcrypt.hashSync(user.password, salt);

  let check_user = await userQuery.getByPseudo(user.pseudo);
  if (check_user.length != 0) {
    res.status(400).json({
      msg: "Account already exists",
    });
    return;
  }

  await userQuery.add(user);
  let result = await userQuery.getByPseudo(user.pseudo);
  let token = jwt.sign({ userId: result[0].id }, process.env.SECRET);
  res.status(200).json({ token: token });
} catch (err) {
  return next(err);
}

}, );

The test with jest:

const axios = require("axios");

const API_URL = process.env.API_TEST_URL;
let TOKEN;

test("POST test register user", async () => {
const data = {
pseudo: "Activity_TEST",
password: "123",
date: "2021-09-29 16:31:25",
};
const url = `${API_URL}/register`;
const response = await axios.post(url, data);
expect(response.status).toBe(200);
expect(response.data).toHaveProperty("token");
TOKEN = response.data.token;
});

The error log:

Jest has detected the following 6 open handles potentially keeping Jest from exiting:
