Page Caching - Errno::EACCES (Permission denied @ dir_s_mkdir - /api)

[AankTia]

Hi, I'm trying to used page caching for my API app with Rails 5.2.1 and actionpack-page_caching 1.1.1,
In ApplicationController if inherit from ActionController::Base, no problem found for cache page,
But if I used ActionController::API, I got error when cache_page like this:

Errno::EACCES (Permission denied @ dir_s_mkdir - /api):

In my ApplicationController:

class ApplicationController < ActionController::API
    include ActionController::RequestForgeryProtection
    include ActionController::Caching

what should I do?

in ApplicationController, just add:

self.page_cache_directory = PAGE_CACHE_PATH
