Hello,

I am trying to make a post request with express-validator, but postman keeps hanging on “sending request…”.

here is my code ----->

const express = require('express');
const router = express.Router();
const { check, validationResult } = require('express-validator/check');


router.post(
  '/',
  [
    check('name', 'Name is required').not().isEmpty(),
    check('email', 'Please include email').isEmail,
    check(
      'password',
      'Please enter a password with 6 or more characters'
    ).isLength({ min: 6 }),
  ],
  (req, res) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({ errors: errors.array() });
    }

    res.send('OK');

  }
);

module.exports = router;

What could be the issue?

Without express-validators postman does work normally and sends the request without delay.

Thanks!
