Need Help with WPGraphQL Caching Issue: WPGraphQL Smart Cache Not Invalidating Cache

Hi everyone,

I'm facing an issue with caching using WPGraphQL and the WPGraphQL Smart Cache plugin on my WordPress site. Here’s a brief overview of the problem I’m encountering:

Issue: I’ve configured WPGraphQL Smart Cache to cache GraphQL queries. However, I’m experiencing the following issues:

1. No x-cache Header: I’m not seeing the x-cache header in the network responses when making GraphQL requests.
2. Cache Not Invalidating: Even though the plugin is activated, updates made in WordPress (e.g., editing posts) are not reflected in the GraphQL queries. The data returned by the queries remains stale.

Steps Taken:

• Verified that WPGraphQL Smart Cache is activated and configured correctly.
• Attempted to manually clear and reset the cache.
• Checked network response headers for cache-related information, but no x-cache header is present.
• Tried using fetchPolicy: "no-cache" in my Apollo Client queries to bypass cache, but it didn’t resolve the issue.

Questions:

1. Has anyone experienced similar issues with WPGraphQL Smart Cache not working or not showing the x-cache header?
2. Are there additional configurations or troubleshooting steps I might be missing?
3. Are there alternative caching solutions for GraphQL queries in WordPress that you would recommend?

consider I use just WordPress in local area with nextjs, in some tutorials I faced wpEngine

I’d appreciate any insights or suggestions from the community. Thank you in advance for your help!
