InternalOAuthError - failed to obtain request token

[elimence]

I am looking to use passport-linkedin in my application. I have successfully implemented same for twitter, facebook and instagram. However with linkedin, I get getting the following error

InternalOAuthError: failed to obtain request token

GET /oauth/linkedin 500 1074ms - 786b

Here's what my code looks like

xports.setup = function (config) {
  var passport = require('passport');
  var LinkedinStrategy = require('passport-linkedin').Strategy;

  passport.use(new LinkedinStrategy({
      consumerKey: config.linkedin.clientID,
      consumerSecret: config.linkedin.clientSecret,
      callbackURL: config.linkedin.callbackURL
    },
    function(token, tokenSecret, profile, done) {
      console.log(token, tokenSecret, profile);
      return done(null, true);
    }
  ));
};

and here's the routing setup

router
    .get('/', 
        function(req, res, next) {
            console.log("[OAuth2:redirect:query]:", JSON.stringify(req.query));
            console.log("[OAuth2:redirect:body]:", JSON.stringify(req.body));
            next();
          },
        passport.authenticate('linkedin', {
        failureRedirect: '/settings/connected-accounts',
        session: false
    }))

    .get('/callback', passport.authenticate('linkedin', {
        failureRedirect: '/settings/connected-accounts',
        session: false
    }), function (req, res){
        res.redirect('/settings/connected-accounts');
    });

Also, I have setup the appropriate endpoints on linkedin as follows;

Authorized Redirect URLs:

    http://testdomain.ngrok.io/oauth/linkedin/callback
    http://localhost:9000/oauth/linkedin/callback
    http://127.0.0.1:9000/oauth/linkedin/callback

Default "Accept" Redirect URL:

    http://testdomain.ngrok.io/settings/connected-accounts
    http://localhost:9000/settings/connected-accounts

I tried each of the above but always had the same error.
I don't know what to do next, I'd really appreciate any help.
Thanks :)

Also having this issue, any luck?

[elimence]

No luck, but recheck your key's, I've had trouble with those in other cases.

[jackcohen5]

Try running npm update and bower update

After running both of those, I got it working again

[elimence]

Ok, will give that a shot, and thanks :)

[jackcohen5]

Did you try running npm update and bower update?

[gauravbansal74]

Thank you for your quick reply.

Hey guys ! I am using Mean IO where they followed OAuth 1. x strategy for LinkedIn....Could you help to overcome this issue

[a455bcd9]

@elimence It seems that you used OAuth2, this package is a strategy for authenticating with LinkedIn using the OAuth 1.0a API. Try using https://github.com/auth0/passport-linkedin-oauth2 instead, it should work.

[askucher]

Dame same issue.

[MyNameIsAlaa]

same issue here! any solution?

[kmokrzycki]

Initially I had very same issue and my problem was the scope.I was asking for non-existing scope r_fullprofile that is not available any more, and funny enough this was failing only occasionally not all the time, there must be some inconsistency at LinkedIn side.

Try to limit you scope just to a single known value.

I had this issue and had to use

https://github.com/jaredhanson/passport-google-oauth2

rather than the basic google auth in the docs to make it work. It looks like the original uses an outdated URL.

[umairjyetoo]

Well I was getting the same error but then i used
var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
instead of .OAuthStrategy ... It worked for me
