'Jest throwing Mongo error - Operation `User._findAndModify()` buffering timed out after 10000ms. But this error only occurs while testing

My code works fine while normal development, but when I am testing it using jest it always throws 400 bad req with error - "Operation User._findAndModify() buffering timed out after 10000ms."

My Code -

const request = require('supertest');
const httpStatus = require('http-status');
const app = require('../src/app');

jest.setTimeout(30000);
describe('POST /v1/login', () => {
    test('should return 200 ', async () => {

      const loginCredentials = {
        "email": "[email protected]",
        "name": "roomi",
        "token": "token"
      };

      const res = await request(app).post('/v1/login').send(loginCredentials);
      console.log('Response Body :', JSON.stringify(res.body, null, 2))
      expect(res.status).toBe(200)
    });
  });

Terminal output -

console.log
    Response Body : {
      "success": false,
      "message": "Operation `User._findAndModify()` buffering timed out after 10000ms",
      "error": {
        "subError": {
          "message": "Operation `User._findAndModify()` buffering timed out after 10000ms"
        },
        "details": "No additional details provided, Check Logs.",
        "isOperational": true,
        "name": "MongooseError"
      }
    }

The database is connected.

usually the error will happen when database is not connected. Try checking whether test environment setup uses the same url to DB as well as db connection code (e.g., mongoose.connect(...) ) executed as part of test loading flow.
