Shopify's GraphQL Admin API version 2026-10 removes the deprecated `priceRule` field from the `DraftOrderDiscountNotAppliedWarning` object. Apps querying `priceRule` in draft order discount warnings (from mutations like `draftOrderCalculate`) must migrate to the direct `discountTitle` and `discountCode` fields before upgrading. This also removes the legacy `PriceRule` object and related types from the public schema in 2026-10 and later. Older API versions continue to expose the field until end of life.
