GraphQL Not Working for "Load More" Functionality on Published Environment

Issue: GraphQL Not Working for "Load More" Functionality on Published Environment

Summary:
The "Load More" functionality using GraphQL queries works correctly in preview mode and local environments but fails on the published GraphQL endpoint. The error message indicates an execution issue with the children query, specifically with the endCursor value.

---

Root Cause:

1. Incorrect Context ID: The published environment may be using the Preview Context ID instead of the Live Context ID in the configuration.
2. Unpublished Items: Items referenced in the query might not be published or available in the Live Experience Edge.
3. Incorrect Cursor Value: The endCursor value may not be valid for the published environment, potentially copied from the Preview environment.

Solution:

1. Update Context ID:

   • Set the correct SITECORE_EDGE_CONTEXT_ID for the Live environment in your hosting provider's environment variables (e.g., Vercel).
   • Redeploy the application to ensure the correct configuration.

2. Verify Published Items:

   • Confirm that all required items are published and available in the Live Edge endpoint.

3. Use Correct Cursor:

   • Run the initial query (children (first: 4)) without the after parameter on the Live endpoint to retrieve the correct endCursor value.
   • Use the returned endCursor for subsequent queries.

4. Test Queries in Published Environment:

   • Verify the GraphQL query directly in the published GraphQL IDE to ensure the configuration works correctly.

By following these steps, the "Load More" functionality should work as expected in the published environment.
