树枝找不到Symfony3服务

Question

I've got the following problem. I've got a service. And I want to use that service in every TWIG template. But it does not find my service.

I get the following error:

ServiceNotFoundException in CheckExceptionOnInvalidReferenceBehaviorPass.php line 58:
The service "twig" has a dependency on a non-existent service "appbundle\service\categoryhandler".

Notice that the service is not camelcased, while it is camelcased in my config.yml.

Here's my config.yml part

# Twig Configuration
twig:
    debug: '%kernel.debug%'
    strict_variables: '%kernel.debug%'
    globals:
        categories: '@AppBundle\Service\CategoryHandler'

I already added PHP templating engine ( found this 'solution' while googling my problem ).

templating:
        engines: ['twig', 'php']

I've followed this documentation of Symfony

Looks like it cannot find your CategoryHandler service.

Has it been registered? Or, has auto loading been enabled? http://symfony.com/doc/current/service_container.html#creating-configuring-services-in-the-container
