Cakephp3 cache duration not expiring

Question

Hello everyone I work with cakephp3 I have implemented the cache from doc but the duration to expire the cache does not apply. I tried to use minutes and hours in the duration but it doesn't work thanks for your help.

Here is my cache configuration

'Cache' => [
    'access_token' => [
    'className' => 'File',
    'duration' => '+2 minutes',
    'path' => CACHE
   ]
],

and here I created my cache with my configuration:

Cache::write("access_token\_$key", $response, 'access_token');

The cache does not expire after 2 minutes, I also tried to use +1 hours instead of +2 minutes but still it does not work
