Estoy tratando de iniciar sesión en Linkedin, tengo este problema.

flask_oauthlib.client.OAuthException: Invalid response from linkedin

this is my callback function.

 @app.route('/login/authorized')
 def authorized():
    resp = linkedin.authorized_response()
    
    # return resp
    
    if resp is None:
        return 'Access denied: reason=%s error=%s' % (
            request.args['error_reason'],
            request.args['error_description']
        )
    session['linkedin_token'] = (resp['access_token'], '')
    me = linkedin.get('people/~/email-address')
    return jsonify(me.data)
