Solve the following python programming problem given the following code:
def add_jade_renderer(config, extension, mako_settings_prefix = 'mako.') : 
    renderer_factory = MakoRendererFactory () 
    config.add_renderer (extension, renderer_factory) 
    def register() : 
        settings = config.registry.settings 
        settings ['{0}preprocessor'.format (mako_settings_prefix)] = preprocessor 
        opts = parse_options_from_settings (settings, mako_settings_prefix, config.maybe_dotted) 
        lookup = PkgResourceTemplateLookup (** opts) 
        renderer_factory.lookup = lookup 
config.action (('jade-renderer', mako_settings_prefix), register) 

    
    

    Fix the buggy line: config.action (('jade-renderer', mako_settings_prefix), register)
