I have the same problem with it. Maybe it just happened recently
Topic summary
Issue: Cart attributes queried in input.graphql return null values within “cart checkout validation” functions, despite working correctly in other extension types (delivery customization, UI extensions) and appearing properly in order details post-checkout.
Timeline & Status:
- Problem emerged suddenly 7-8 days ago for multiple developers
- Shopify’s team (via Liam) confirmed the issue was on their end and deployed a fix
- Some users reported the problem resolved automatically after the fix
- Recent reports indicate the issue persists for certain stores, even on the latest API version (2024-10)
Key Details:
- Affects only cart checkout validation functions; other extension types retrieve cart attributes successfully
- No code changes preceded the issue
- Reinstalling apps or toggling checkout rules did not resolve it
- Users are querying cart attributes like
address_type,address_profile, and custom handles
Current State: Unresolved for some developers who are requesting further investigation from Shopify support.
