Tech gurus over to you guys...

Head to stackoverflow for ur solution. How I wish it's PHP , would've helped u out.

Use anti bugging.

How can i use it ?

It seems it has to do with the bcrypt package.
Confirm that password is not undefined.

Unfortunately I can't help, but I can feel your frustration

Can you share your repo? Is it public?

From the error log, e dey shout bcrypt! Hence, I'll suggest looking deep into the module and the argument type.
Secondly, ensure your promise is settled so the fulfilled value of the promise will be regarded or treated as a return value... (an actual value)

Since you say you don check SO, please share the repo link. Make we dey learn as we dey solve problems.

It's pointing to line 21.
const salt = await bcrypt.genSalt(10);
const hashedPasssword = await bcrypt.hash(password, salt);

https://www.npmjs.com/package/bcryptjs Please checkout their docs

ReactJs:

Good evening sir
As a newbie in backend development with nodejs, I've learnt concepts like routing.
What more should I know
Most of what will be needed when working as a backend end developer, not just routing.

Was your password field in your model class set this way?

password: {
type: String,
select: false,
},
setting a select attribute as false prevents passwords from being returned in the JSON response object
so I think your password isn't returned from the query. You can try replacing that line with

const existingUser = await User.findOne({ email }).select('+password');


or better still place a line break there and run on debug mode to monitor the returned values

JavaScript mastery has a backend developer roadmap

I think it has to do with the bcrypt module. You did not handle it well.
Exactly as ReactJs has pointed out.
const salt = await bcrypt.genSalt(10);
const hashedPasssword = await bcrypt.hash(password, salt);

Do this

Const hashPassword = bcrypt.hashSync(password, 10)

That should hash the password correctly.

The problem is from bcrypt, what you did was wrong. You can just hash password like that

Have u been able to solve it??

I believe you are right

He can also use crypto-js module.
