Adobe Commerce on cloud infrastructure v2.3.5 GraphQL caching invalidation not working

This article provides a patch for the issue where GraphQL GET request returns outdated information if the customer changes product information.

Affected products and versions

Adobe Commerce on cloud infrastructure v2.3.5.

Issue

GraphQL requests are cached by Fastly, and the cached version is retrieved for each subsequent request from Fastly. When a product is re-saved in the Adobe Commerce backend, the Fastly cache should invalidate when a product is updated. However, it remains valid.

Steps to reproduce:

1. Trigger the following GraphQL request to get products for certain category like:

   GET http:///graphql?query={products(currentPage:1,pageSize:6,filter:{web_ready:{eq:"1"},category_id:{eq:"1521"}}){total_count,items{__typename,id,sku,name}}}
    

2. Re-save one of the products retrieved by the request above in the Commerce Admin.
3. Trigger the request again.

Expected results:

The X-Cache header contains MISS.

Actual results:

The X-Cache header contains HIT, which means the response is cached.

Solution

Disable GraphQL product cache with the patch provided in this article.
