validation bug

[talk2sohail]

During the server side validation of the user data input...it return the response::

` const result = Joi.validate(req.body, schema);
if (result.error) {
return res.status(400).json(result.error);
}

if (!req.value) { req.value = {}; }
req.value['body'] = result.value;
next();
`

response is received but the user is saved in the DB with corrupted data.
would like to contribute. :-)
