Setting permitsSkuSharing argument to false when creating a fulfillment service returns an error

With the 2025-10 API version, the permitsSkuSharing argument has been updated for both the fulfillmentServiceCreate mutation and the FulfillmentService#create REST endpoint to return an error if a false value is passed in. Non-SKU sharing fulfillment services have been deprecated, and this pushes us in the direction of making all Fulfillment Services Sku sharing enabled.

If your app or service is currently passing in a false value, please update it to send in true instead, or omit this parameter entirely. This change means that any new fulfillment services that are created can share SKUs with other locations and ensures future compatibilty with our systems.
