AuthMiddleware / AccessToken is not a object.

[traedamatic]

Hello,
i run into a strange behavior. First I will explain the scenario. I use the Laravel framework and created a login route for Instagram (as mentioned in the docs). That works fine: The server redirects to Instagram and Instagram does redirect back to correct redirect_url, i entered.

Now I call the setAccessToken with the code returned from Instagram. Note: The variable $instagramManager is a proxy/facade to a Instagram Client instance. (I use this package for that https://github.com/vinkla/laravel-instagram)

$code = $request->query('code', false);

if ($code === false) {
      return response()->redirectTo($instagramManager->getLoginUrl());
}

 $token = $instagramManager->getAccessToken($code);

Everything works fine. I can see the token stored in the variable $token.
Now I am trying to get the users information:

$instagramManager->users()->get()

And the following error appears:

Call to a member function getToken() on string in /var/www/html/vendor/larabros/elogram/src/Http/Middleware/AuthMiddleware.php on line 36

Strange. Some further inspection:

In the Client.php I see from line 240 following code:

 public function setAccessToken(AccessToken $token)
    {
        $this->container->get('config')
            ->set('access_token', json_encode($token->jsonSerialize()));
    }

So the access-token will be saved into the config under the key access_token and very important as json encoded string.

In the AuthMiddleware.php on line 33 I see following code:

$uri = Uri::withQueryValue(
            $request->getUri(),
            'access_token',
            $this->config->get('access_token')->getToken()
        );

What this does is getting the access-token from the configuration and trying to call directly the getToken method on the returned access-token. As we save before the the access_token is a json_encoded string. Therefore it is not possible to call the method getToken.

Do i miss here anything or is this a bug?
