The class Drupal\Core\Cache\CacheableDependencyInterface does not exist. Did you forget a USE statement, or did you not list all dependencies?

    // cache is disabled through the service parameters.

The variable $config seems to never exist, and therefore empty should always return true. Did you maybe rename this variable?
