Error 500 when using Redis Object Cache

Sometimes, the add to cart function runs on a 500 error, when using Redis. The issue is that the plugin temporary stores cart item key on get_option(‘xoo_cp_added_cart_key’), set_option(‘xoo_cp_added_cart_key’) and its cached by Redis.
Flusing Redis solves the issue.

Is there any other way to save that option temporary (like session or something), as wp_options is bad practice
