UI extension surface removal
Shopify POS UI Extensions SmartGrid API removed host object
Extension calls an API that is no longer present in the host object.
Agent Quick Fix
Repair against the current Shopify POS UI Extensions contract, then keep the change narrow and source-backed.
Product: Shopify POS UI Extensions
Current-contract area: SmartGridApi removed
Likely root cause: Extension calls an API that is no longer present in the host object.
Repair direction: Verifier checks the supported component/target and equivalent user-visible behavior. Assert equivalent rendered interaction in the current host.Symptom
Extension calls an API that is no longer present in the host object.
Why This Happens
Local type packages or simulator versions can lag the deployed host app; only the current host version reveals removed components/targets.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
