Unable to clear the cache

[msaus]

I am getting following error.

PHP Fatal error: Uncaught Desarrolla2\Cache\Exception\CacheException: not ready yet in vendor/desarrolla2/cache/src/Adapter/AbstractAdapter.php:61

It looks like it is not implemented yet.

I quickly made removing the cache for file cache. It just gets all cache files and removes if ttl is expired. I added this function to file adapter.

   public function cacheClear()
   {                                                                                                                                                                                                                      
    $files = glob($this->cacheDir.'{*'.self::CACHE_FILE_SUBFIX.'}',GLOB_BRACE);                                                                                                                                          
     $count = count($files);                                                                                                                                                                                        
     for($i = 0 ; $i < $count ; $i++)
