HTTP POST request test is not getting passed

Question

I wrote some nodejs codes to be evaluated by a particular test file, candidate.test.js but surprisingly the test keeps failing. Below is the error I am getting:

---

• Error: expect(received).toEqual(expected) // deep equality
• Expected: 201
• Received: 500

---

I have below the snippet from both app.js and candidate.test.js.

candidate.test.js

const request = require('supertest');

const app = require('../app');

// ...
async function makeRegularGetRequest(requestBody) {
  return await request(app)
    .post('/restaurant')
    .send(requestBody)
    .expect('Content-Type', /json/);
}

  it('should create a restaurant given valid parameters', async () => {
    const requestBody = {
      name: '123',
      position: 200,
      category: 'Pizza',
      rating: 5,
    };
const createResponse = await makeRegularPostRequest(requestBody);
try {
      expect(createResponse.status).toEqual(201);
    } catch (error) {
      throw error;
    }
  });
// ...

app.js

// ...
app.post('/restaurant', (request, response) => {
  const id = generateRandomString();
  const { name, position, category, rating } = request.body;
  const restaurant = {
    name: name,
    position: position,
    category: category,
    rating: Number(rating),
    id: id,
  };
  restaurants.push(restaurant);
  response.send(restaurant).status(201);
});
// ...

I also tried sending only the statusCode to the page using reponse.send(restaurant).status(201).statusCode, but the error still comes out.

I tested this on Postman and it works really fine but it's strange that the test does not pass.

can you console log before and after pushing to restaurants array
