error:"UnhandledPromiseRejectionWarning: Error: Invalid message options" in nodejs - node.js

Question

I am trying to call registerValidation function that is defined in file validation.js from auth.js, but error appears that
UnhandledPromiseRejectionWarning: Error: Invalid message options
Can anyone tell me why and how to correct it?
auth.js
const router = require("express").Router();
const User = require("../model/User")
const {registerValidation} = require("./validation")
router.post('/register', async(req, res)=>{
//Lets validate the data
//error appears here
const {error} = registerValidation(req.body);
if(error){
return res.status(400).send(error.details[0].message)
}
const user = new User({
name:req.body.name,
email:req.body.email,
password:req.body.password
});
try{
const savedUser = await user.save();
res.send(savedUser);
}catch(err){
res.status(400).send(err)
}
})
module.exports = router;
validation.js
//VALIDATION
const Joi = require("#hapi/joi")
const registerValidation = (data) => {
const schema = Joi.object({
name:Joi.string().min(6).required(),
email:Joi.string().min(6).required().email(),
password:Joi.string().min(6).required()
});
return schema.validate(data, schema)
}
const loginValidation = data =>{
const schema = Joi.object({
email:Joi.string().min(6).required().email(),
password:Joi.string().min(6).required()
});
return schema.validate(data, schema)
}
module.exports = {registerValidation, loginValidation};

Answer 1

You need to wrap your functions inside an object and then export that object, like in the following example:
const registerValidation = (data) => {...}
const loginValidation = (data) => {...}
module.exports = {
registerValidation,
loginValidation
}
Alternatively, since module.exports is an object itself, you could do something like the following:
const registerValidation = (data) => {...}
const loginValidation = (data) => {...}
module.exports.registerValidation = registerValidation;
module.exports.loginValidation = loginValidation;

Answer 2

the registerValidation and loginValidation function should be like given below
const Joi = require("#hapi/joi");
const registerValidation = (data) => {
console.log("body ", data)
const schema = Joi.object({
name:Joi.string().min(6).required(),
email:Joi.string().min(6).required().email(),
password:Joi.string().min(6).required()
});
return schema.validate(data) //change here
}
const loginValidation = data =>{
const schema = Joi.object({
email:Joi.string().min(6).required().email(),
password:Joi.string().min(6).required()
});
return schema.validate(data) //change here
}
module.exports = {registerValidation, loginValidation};
