Answer 1

it's not a bug with express-validators, it is the way how validators work in case of middlewares.

At the root level create a directory called utils and inside the directory a validation.js file and add your validation code in it:

utils/validation.js

const { check } = require('express-validator');
exports.addPostCheck = [
    check('title', 'The title field id required')
    .not()
    .isEmpty(),
    check('excerpt', 'The excerpt field id required')
    .not()
    .isEmpty(),
    check('body', 'The full text field id required')
    .not()
    .isEmpty()
];

In the routes/dashboard.js include validation.js

const validator = require('../../utils/validation.js');

Change Line No: 16
From: 
router.post('/post/add', dashboardController.addPost);
To:
router.post('/post/add', validator.addPostCheck, dashboardController.addPost);

In the controllers/admin/dashboard.js

Change Line No: 2
From: 
const { check, validationResult } = require('express-validator');
To:
const { validationResult } = require('express-validator');

Remove Line Nos 29 to 39.
