ACF custom fields taxonomy error

    Hi,
    I am experiencing issues with Advanced Custom Fields and Redis Object Cache in my WooCommerce site. When Redis object cache is flushed, the product pages that rely on ACF taxonomy fields (used for filtering related posts) show 500 server error pages until I manually save a product with problem in the admin, which refreshes the cache. The problem only occurs for products where the ACF taxonomy field has been set previously. Products without this field do not have cache issues. I have a workaround that manually primes the cache for products with ACF fields, but it is not fully automated.
    How to solve this issue? Object cache pro would solve this issue out of the box? As I know it has cache priming function, might be similar what I am using right now with code snippets.

    A 500 error would mean there might be a full PHP error in your logs. Can you post those?

    Just for the record, I could solve the problem with the local JSON feature in ACF.

    With this setting ACF does not consume that much php memory.
