problem with Builder

[R3B4T0]

How I can create the params ClaimsFormatter and Encoder to pass them to Builder constructor??

Error: "Too few arguments to function Lcobucci\JWT\Token\Builder::__construct(), 0 passed in C:\xampp\htdocs\symfony\proyectoBassClefSymfony\src\Controller\ChatController.php on line 27 and exactly 2 expected"

Code:

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

By default, the Builder is something you can get from a Lcobucci\JWT\Configuration instance, as explained in https://github.com/lcobucci/jwt/blob/207955dfbce28b4fbdc12367fbccf9546c66eb2d/docs/issuing-tokens.md

The Configuration#builder() uses a closure internally to give you a clean Builder each time:

jwt/src/Configuration.php

Lines 104 to 107 in 207955d

	public function builder(?ClaimsFormatter $claimFormatter = null): Builder
	{
	return ($this->builderFactory)($claimFormatter ?? ChainedFormatter::default());
	}

jwt/src/Configuration.php

Lines 47 to 49 in 207955d

	$this->builderFactory = static function (ClaimsFormatter $claimFormatter) use ($encoder): Builder {
	return new Token\Builder($encoder ?? new JoseEncoder(), $claimFormatter);
	};

Thank you! But, What is the $container?? Because I get the error that the variable is not initialized
