TypeError: Невозможно прочитать свойство 'apply' из undefined в NodeJS с помощью модульного тестирования JEST

Я новичок в шутливом модульном тестировании, а также NodeJS, и я пытаюсь протестировать мой API, используя следующий код. 

const request = require('supertest');
const quick_registration = require('../../../routes/register/quick_registration_of_user')

describe('Quick Registration of users', () => {
    beforeAll(() => {
        con.connect();
    });

    describe("GET / ", () => {
        test("It should respond with an array of students", async () => {
          const response = await request(quick_registration).get("/api/quickregistration");
          expect(response.status).toBe(200);
        });
      });
})

Но тест не проходит и выдает ошибку 

 FAIL  tests/routes/register/quick_registration_of_user.test.js
  Quick Registration of users
    GET /
      × It should respond with an array of students (20ms)

  ● Quick Registration of users › GET /  › It should respond with an array of students

    TypeError: Cannot read property 'apply' of undefined

Ran all test suites.
Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.
