A GraphQL query error (code 1675030) occurs on the Worlds inventory page in the Developer Dashboard when editing a creatable item. The error is specifically with the OCDevManageWorldsInventoryQuestRewardTiersNotificationBannerLazyQuery, which is used to power the quest reward tiers notification banner component. The error message indicates "Error performing query" and is caught in the OCDevManagePlaceholder.react module. This issue appears to be a server-side query failure that prevents the notification banner from loading during inventory item editing workflows.
