Builder /Token Problem

[pierremartel]

I try to implement a Real time Chat in my app on Symfony with Mercure but i have some problem with the builder . They give me this error:

Here my code :

So i try to change my code with the configuration instance because i think it's about my version of Lcobucci (v.4) and look at the documentation .

And now i have this error :

Cannot autowire service "App\Controller\IndexController": argument "$config" of method "__construct()" references class "Lcobucci\JWT\Configuration" but no such service exists.

What is wrong with my code ?

You are missing a service definition that leads to a Lcobucci\JWT\Configuration instance, as the exception states.

I try that at the line 26- 27 in my service.yaml but doesnt work :

Is it right ?

i have this error now but i dont understand what to do :

The controller for URI "/" is not callable: Controller "App\Controller\IndexController" cannot be fetched from the container because it is private. Did you forget to tag the service with "controller.service_arguments"?

[Ocramius]

No, that way you configured the IndexController to be an instance of Lcobucci\JWT\Configuration.

Please make sure that you study the Symfony dependency injection documentation.

What you want is a n Lcobucci\JWT\Configuration service, configured in all its relevant details.
