$container of type object<Interop\Container\ContainerInterface> is not a sub-type of object<Zend\ServiceManager\ServiceLocatorInterface>. It seems like you assume a child interface of the interface Interop\Container\ContainerInterface to be always present.

The parameter $options is not used and could be removed.
