Sign in with LinkedIn is deprecated, here you have the new OpenId method

[adantart]

"Sign In with LinkedIn" is deprecated, use "Sign In with LinkedIn using OpenID Connect" instead

Linkedin changed its authentication method from Sign in with LinkedIn to Sign in with LinkedIn using OpenID Connect, since then the new app registered recently had this error.

So this changes has to be made on the LinkedIn Provider:

1. in services/config, change the linkedin scopes from whatever you have (probable ['r_emailaddress', 'r_liteprofile']) to, at least, these ones:

['openid', 'profile', 'email']

2. In LinkedInProvider.php file:

• change the $scopes allowed
• getByUserToken just need the basicProfile
• getBasicProfile does not need extra PARAMS
• getEmailAddress is not longer needed (it comes in the "userinfo" api method)
• the mapUserToObject is now easier

My new LinkedInProvider file is now like this:

<?php

namespace Laravel\Socialite\Two;

use GuzzleHttp\RequestOptions;
use Illuminate\Support\Arr;

class LinkedInProvider extends AbstractProvider implements ProviderInterface
{
    /**
     * The scopes being requested.
     *
     * @var array
     */
    protected $scopes = ['openid', 'profile', 'email'];

    /**
     * The separating character for the requested scopes.
     *
     * @var string
     */
    protected $scopeSeparator = ' ';

    /**
     * {@inheritdoc}
     */
    protected function getAuthUrl($state)
    {
        return $this->buildAuthUrlFromBase('https://www.linkedin.com/oauth/v2/authorization', $state);
    }

    /**
     * {@inheritdoc}
     */
    protected function getTokenUrl()
    {
        return 'https://www.linkedin.com/oauth/v2/accessToken';
    }

    /**
     * {@inheritdoc}
     */
    protected function getUserByToken($token)
    {
        $basicProfile = $this->getBasicProfile($token);
        // $emailAddress = $this->getEmailAddress($token);

        return $basicProfile;
        return array_merge($basicProfile, $emailAddress);
    }

    /**
     * Get the basic profile fields for the user.
     *
     * @param  string  $token
     * @return array
     */
    protected function getBasicProfile($token)
    {
        $response = $this->getHttpClient()->get('https://api.linkedin.com/v2/userinfo', [
            RequestOptions::HEADERS => [
                'Authorization' => 'Bearer '.$token,
                'X-RestLi-Protocol-Version' => '2.0.0',
            ]            
        ]);
        return (array) json_decode($response->getBody(), true);
    }

    /**
     * {@inheritdoc}
     */
    protected function mapUserToObject(array $user)
    {

        $preferredLocale = Arr::get($user, 'locale.language', []);
        $firstName = Arr::get($user, 'given_name', '');
        $lastName = Arr::get($user, 'family_name', '');
        $avatar = Arr::get($user, 'picture', []);
        $originalAvatar = $avatar;

        return (new User)->setRaw($user)->map([
            'id' => $user['sub'],
            'nickname' => null,
            'name' => $firstName.' '.$lastName,
            'first_name' => $firstName,
            'last_name' => $lastName,
            'email' => Arr::get($user, 'email'),
            'avatar' => $avatar,
            'avatar_original' => $originalAvatar,
        ]);
    }
}

Please, make the changes in the repository (after reviewing/updating/improving) so others can retrieve this new method.

Thank you !

Same issue here, once I replace the code above, worked perfectly. If no issues, i'll try to get a PR in later.
