Agent Quick Fix

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

Product: Shopify Returns GraphQL
Current-contract area: Generated GraphQL types still model singular lineItem
Likely root cause: Deserializer/business logic fails when migrated query returns a list.
Repair direction: Verifier exercises the changed field/status/enum plus an unaffected endpoint to prevent a brittle one-off patch. Verify all associated line items and ordering/aggregation behavior.

Symptom

Deserializer/business logic fails when migrated query returns a list.

Why This Happens

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

Verification

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.
