I'm getting the error "return binding.PBKDF2(password, salt, iterations, keylen, callback); ^ TypeError: Not a buffer"

Question

See the full error code below:

crypto.js:601
    return binding.PBKDF2(password, salt, iterations, keylen, callback);
                   ^
TypeError: Not a buffer
    at pbkdf2 (crypto.js:601:20)

I'm working the Amos Haviv's book MEAN Stack Development and am in chapter 6 - if anyone cares.

Here is the code that is throwing the error (see comments for line numbers):

UserSchema.pre('save', function (next) {
    if (this.password) {
        this.salt = new Buffer(crypto.randomBytes(16).toString('base64'), 'base64');
        this.password = this.hashPassword(this.password);
    }
    next();
});
UserSchema.methods.hashPassword = function (password) {
    return crypto.pbkdf2Sync(password, this.salt, 10000, 64).toString('base64');//line 59
};
UserSchema.methods.authenticate = function (password) {
    return this.password === this.hashPassword(password);//line 63
};

So, it turns out that I was populating the Mongo db with a non-hashed string for the password.

Once I logged in with a hashed password from the db, it worked fine.

Now I need to learn error checking...
