Fix the session issue with Redis cache

Created by Rosa Truong, Modified on Mon, 22 Jun 2020 at 03:11 PM by Rosa Truong



We have then made a fresh installed Magento 2.3.4 of your latest checkout, tested it, and after purchase landed in an empty cart.

Something seems to be bugging in the module.


This issue is caused due to the session error with the Redis cache. 
Our module processes the data longer than the Redis does; so the Redis session success of the cart is timed out. And it causes the issue.
To fix the issue, we would like to give you the solutions to increase the value of config "break_after_frontend" (increase the time of Redis cache from 5 to 15 seconds)

+ Option 1: Run this command php bin/magento setup:config:set --session-save=redis --session-save-redis-break-after-frontend=15 

(Please take a look at this article for more information:

+ Option 2:  Change the value config "break_after_frontend" of Redis session on this file app/etc/env.php (attachment below) 

If you have any issues, please don't hesitate to contact us.
