Jest detects open handle DNSCHANNEL if node package got is used

I'm programming server in Node.js v12.18.3, using Express framework. My code uses Jest for unit testing. In one of my module, I've used the got package. But it's not used in any unit test.

I've designed the following minimal test:

const { app } = require('../app');
const { mongoose, database } = require('../database/database');
const api_dict = require("../api_dictionary");
var User = require('../models/user');

describe("===== POST " + api_dict.users_create + " Tests ===== ", () => {

    var db;

    beforeAll(async () => {
        await mongoose.connect(database, { useNewUrlParser: true, useUnifiedTopology: true });
        db = mongoose.connection;
    });

    afterAll(async () => {
        await db.close();
    });

    test("Create user", () => {
    });
});

I'm using jest --detectOpenHandles command to detect open handles. Jest detected one:

npm test

> jetfire@0.0.0 test E:\Projects\github\project_name
> cross-env NODE_ENV=test jest --detectOpenHandles

 PASS  tests/tests.js (8.118 s)
  ===== POST /user/create Tests =====
    √ Create user (1 ms)

Test Suites: 1 passed, 1 total

Jest has detected the following 1 open handle potentially keeping Jest from exiting:

  ●  DNSCHANNEL

      at new CacheableLookup (node_modules/cacheable-lookup/source/index.js:75:14)
      at Object.<anonymous> (node_modules/got/dist/source/core/index.js:29:24)
      at Object.<anonymous> (node_modules/got/dist/source/as-promise/types.js:16:16)

How to ensure that this handle is closed when all unit tests are ran?
