The service "security.context_listener.0" has a dependency on a non-existent service "fos_user.user_manager"

Question

I have been having this error and I don't know what is wrong with my code. I have checked for various ways to correct it but I can't seem to find.

I keep getting this error:

The service "security.context_listener.0" has a dependency on a non-existent service "fos_user.user_manager"

This is services.yaml

                            # The best practice is to be explicit about your dependencies anyway.

This is security.yaml

        logout:       true

    - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/admin/, role: ROLE_ADMIN }

Please I would need some help to know where exactly the error is coming from. Thanks guys.

There's an error in your security configuration. The provider shouldn't be user_manager.

Change it to:

security:
    providers:
        fos_user:
            id: fos_user.user_provider.username
