I'm trying to update symfony from 3.4 to 6.0.1
And i got an error
Class "" used for service "security.listener.user_checker.integration" cannot be found.
I have this error for each blocks in firewalls section
integration:
pattern: ^/integration
host: %base_host%
stateless: true
custom_authenticators:
- integration.authenticator.token
provider: integration_provider
and
So ChildDefinition has no class(but has parent)
And I can't understand how it should work. Which class should be returned in RegisterListenersPass and where it should be set
