Uncaught TypeError: Cannot read property 'sigBytes' of undefined

I'm trying to generate a session after initialising QB with a token genreated from the server.

The token seems valid, when I use it on curl requests I get back the correct info, but when doing QB.createSession I'm getting an error, the following is the frontend code

QB.init(token, {debug:true});
QB.createSession(function(err, result){
  console.log(err, result)
});

//Uncaught TypeError: Cannot read property 'sigBytes' of undefined

As far as I understand, the code above should work perfectly, when I try doing the init with the secrets/keys it works flawlessly.

Server code (python) to generate the token:

class QuickBlox(object):
    """
    base class to be used with all QB classes
    """
    # settings
    qb_settings = settings.QUICKBLOX
    application_id = qb_settings["ID"]
    auth_key = qb_settings["KEY"]
    auth_secret = qb_settings["SECRET"]
    version = qb_settings["VERSION"]

    # API URLs
    api_root = "https://api.quickblox.com/"
    users_url = api_root + "users.json"
    login_url = api_root + "login.json"
    session_url = api_root + "session.json"
    content_type = "application/json"


class QBApplication(QuickBlox):
    """
    class for interacting with the QuickBlox Application API
    """
    def __init__(self):
        self.app_token = self.get_application_token()

    def get_application_token(self):
        """
        this will return session data from QuickBlox.
        """
        nonce = str(random.randint(1, 10000))
        timestamp = str(int(time.time()))

        signature_raw_body = ("application_id=" + self.application_id + "&auth_key=" + self.auth_key + 
                "&nonce=" + nonce + "&timestamp=" + timestamp)

        signature = hmac.new(self.auth_secret.encode(), signature_raw_body.encode(), sha1).hexdigest()

        params = {
            'application_id': self.application_id, 
            'auth_key': self.auth_key,  
            'timestamp': timestamp, 
            'nonce' : nonce,
            'signature' : signature
        }

        response = requests.post(self.session_url, params=params)
        session_data = response.json()
        return session_data["session"]["token"]

Any insight on why this might be happening? I would really appreciate it!

Apparently the SDK does not like when you're passing options as the second argument when logging in with a token, might be a bug?

[soulfly]

Actually if you use QB.init then I don't see any cases when you also need to use QB.createSession

Anyway We will also check this case

Hi, Soulfly,

May I ask how you not createSession to do login? There is no many doc talked the scenario about what functions we shall called, and I am always do
call QB.init then
call createSession to pass in login user information.

It seems I cannot call QB.login only after QB.init without QB.createSession? So I guess createSession is very important?

@soulfly Regarding the first part

QB.init(id, key, secret, options);
QB.init(token, options);

The first one is the documented version, after you mention using Tokens for auth, the second one makes sense but it fails as, I assume, is trying to use options as key, thus, provoking the sigbytes error.

Regarding the createSession

From the documentation I took away that you need to createSession after the init,

http://quickblox.com/developers/Javascript#Oh.2C_please.2C_please_show_me_the_code

It was unclear to me that you shouldn't createSession after initialising with token, now, createSession after

QB.init(id, key, secret);
QB.createSession(userParams, callback);

Works perfectly, I was able to make the first proof of concept this way and createSession worked perfectly, after migrating to

// token is an app token
QB.init(token);

One would expect createSession to still work, and it doesn't which causes some confusion.

Just doc issues I guess?, anyways, everything seems to be working perfect now after those hurdles.

Cheers!

@charlieshin you can use QB.users.login

@tmayr
we are reviewing completely JS docs at the moment, it will be a new doc set soon, sorry for this

I also have same problem

QB.init(appId, authKey, authSecret);
QB.createSession(QB, (err,data)=>{

})
