Problem with JWT/Builder

[R3B4T0]

The error: Cannot instantiate interface Lcobucci\JWT\Builder

My program:

use Lcobucci\JWT\Signer\Hmac\Sha256;
use Lcobucci\JWT\Signer\Key;
use Lcobucci\JWT\Builder;

public function chat()
    {
        $username = $this->getUser()->getUsername();
        $token = (new Builder())
            ->withClaim('mercure', ['subscribe' => [sprintf("/%s", $username)]])
            ->getToken(
                new Sha256(),
                new Key($this->getParameter('mercure_secret_key'))
            )
        ;

        $response = $this->render('conversacion/index.html.twig', [
            'controller_name' => 'UsuarioController'
        ]);

        $response->headers->setCookie(
            new Cookie(
                'mercureAuthorization',
                $token,
                (new \DateTime())
                ->add(new \DateInterval('PT2H')),
                '/.well-known/mercure',
                null,
                false,
                true,
                false,
                'strict'
            )
        );

        return $response;
    }

You want to use Lcobucci\JWT\Token\Builder, not use Lcobucci\JWT\Builder

Thank you for your help!

[lcobucci]

It looks like you're migrating from v3 to v4, maybe https://lcobucci-jwt.readthedocs.io/en/stable/upgrading/ can help =)

[mehad022]

thank you soooo much for referring version migration guide here, it help me a lot!

[lcobucci]

Glad to hear that! It's quite some work to keep that guide relevant ❤️

I might follow the same auto as R3B4T0 because I have the same code but after changed use Lcobucci\JWT\Token\Builder I get : Too few arguments to function Lcobucci\JWT\Token\Builder::__construct(), 0 passed in /Users/thibaudrobillardDesktop/AFPA/lbchat/src/Controller/IndexController.php on line 20 and exactly 2 expected
I can't find the solution please help

[lcobucci]

That's a different problem, probably you have the new major version but didn't update your code.

The builder has required parameters as of v4. The config object makes it easier to instantiate it. However if you don't want to use it you will need to pass the necessary types.

Can the problem come from mercure ?

It seems like it comes from your code
