No matter what you insert as deliveryTime.warehouseBasedDeliveryTimes.carrierService, it will always be rejected. Setting the value via Merchant Center UI works.

Please try your request using the APIs explorer, and if you don't see the issue there as well, then the problem is in the client libraries. However, as these client libraries are generated from the API, the issue is probably in the way the request is being formed. This repository is only to support the client libraries themselves, not the APIs or their usage.
