## Combined Listings update mutation error improvements

Starting with the Admin API version 2025-01, we've introduced new error codes for the `combinedListingUpdate` mutation. These enhancements aim to provide clearer feedback when incorrect data is submitted.

- The `missing_option_values` error occurs when the `optionsAndValues` field is required but not provided in the request.
