Circular reference detected for service…

Hi,

I’m currently integrating PhpFastCache module to Drupal 8.2 (sources link), and i’m trying to figure out where those error comes from (About 4 in a row):

Circular reference detected for service "cache.backend.phpfastcache", path: "http_kernel -> http_middleware.negotiation -> http_middleware.reverse_proxy -> http_middleware.page_cache -> cache.render -> cache.backend.phpfastcache -> config.factory -> config.storage -> cache.config".

Aside of the module itself, there’s another modification in settings.php:

$settings['cache']['default'] = 'cache.backend.phpfastcache';

Does I am doing it wrong ?

Cheers,
Georges
