TypeError: Cannot read property '_id' of undefined about beerlocker HOT 10 OPEN

@LuizHAP

Your missing the isAuthenticated function that need to be added for each call to our API

From the tutorial " The last piece is to update our server.js file to include the passport package, initialize it with our express app, and call the isAuthenticated function for each call to our API. Open up server.js and update it as follows."

Hi Calvin,

the error indicates, that the authorization was not done correctly. Typically the req.user is set during the auth process.
May be just the authorization when you try to post the data is missing ?

@TheFive i get the same error

from beerlocker.

wich beerlocker server are you working with 1,2,3...

from beerlocker.

@TheFive 3.2

from beerlocker.

you should add more information, when the error occurs (which version, which step in the blog you are evaluating).
Just a hint, where you can search. In the auth file, the user is taken from the database:
https://github.com/scottksmith95/beerlocker/tree/master/beerlocker-3.2/controllers
The function User.findOne retrieves the users from the database.
just add a console.log(user) in line 10, and you can see, what the result is.

(i assume, there is no user, so req.user is NULL at the stage, where the error occurs)

Thats typically, how i learn, put as much console.log in the source as you need to understand, what is going on.

@TheFive Ok. I put one user, and i can get them when i GET /api/users

[
  {
    "_id": "59166bf3d4de2b11707adbd8",
    "username": "luiz",
    "password": "$2a$05$JoE8wWw1uZ5eAC8w26PYzudMmRdj8.G3sAnU7fU5sHKsNe613GEta",
    "__v": 0
  }
]

When i can GET /api/beers, catch that error above. I don't understand how i can use that authentication.

Thanks @TheFive for the head-up

I get this error at frontend. It causes due to, it is not executing state means isAuthenticated unlike this const { user, token } = isAuthenticated();
just add 'isAuthenticated()' in event like submit, It works !!
For backend all private or protected routes must include isSignedIn, isAuthenticated, or specific user group auth, middleware must include
