Symfony2 AuthenticationCredentialsNotFoundException @Route

Question

AuthenticationCredentialsNotFoundException in classes.php line 2876:

The token storage contains no authentication token. One possible reason may be that there is no firewall configured for this URL.

I tried everything I could find on Stack Overflow, GitHub and Google. Nothing worked.

Lesson learned: Always check the log files.

tail -f app/logs/dev.log

Found this:

...[Semantical Error] The annotation \\"@Route\\" in method Ambry\\TumorNextAPIBundle\\Controller\\DefaultController::indexAction() was never imported. Did you maybe forget to add a \\"use\\" statement for this annotation?...

I was missing the following use statement(s):

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

In the following code:

<?php

namespace Ambry\TumorNextAPIBundle\Controller;

use Symfony\Component\HttpFoundation\Request;

use Ambry\BioToolsBundle\Controller\ApplicationController;

class DefaultController extends ApplicationController
{
    /**
     * @Route("/", name="tumornext" )
     * @Method({"GET","POST"})
     * @Template
     */
    public function indexAction(Request $request)
    {
        return array();
    }
}

Lesson learned: Always check the log files.

tail -f app/logs/dev.log
tail -f app/logs/dev.log | grep CRIT
tail -f app/logs/dev.log | grep ERROR
tail -f app/logs/dev.log | grep INFO

In this case, you're missing use statement(s):

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
