tryGetDestination() fails with "Failed to get destination" for NoAuthentication+IAS destination in subscriber tenant context

Bắt đầu từ DestinationAccessor.getLoader().tryGetDestination và so sánh đường dẫn phân giải của nó với DestinationService.getAllDestinationProperties(). Tái hiện trường hợp subscriber-tenant bằng các thuộc tính NoAuthentication và IAS đã nêu, sau đó truy vết lý do quá trình phân giải đầy đủ thất bại trong khi metadata vẫn được lấy thành công. Được xem là hoàn tất khi tryGetDestination trả về destination mà không trao đổi user token và giữ nguyên các thuộc tính liên quan đến IAS.

Describe the Bug

When calling DestinationAccessor.getLoader().tryGetDestination("OneSimAPI_Destination") in a subscriber tenant context, the SDK fails with "Failed to get destination." for a destination configured with
Authentication=NoAuthentication and IAS-based M2M properties (cloudsdk.ias-dependency-name, tokenService.body.url).

The same destination is successfully returned by DestinationService.getAllDestinationProperties() (metadata-only call). The failure happens only during the full resolution via tryGetDestination.

This works correctly for another tenant on the same landscape with the same destination configuration (same auth type, same dependency name, different tokenService.body.url).

Steps to Reproduce

1. Configure a BTP destination in a subscriber subaccount with:
   • Authentication: NoAuthentication
   • cloudsdk.ias-dependency-name: sim-supplier-search-api
   • tokenService.body.url: https://.accounts.ondemand.com
2. Call DestinationAccessor.getLoader().tryGetDestination("OneSimAPI_Destination") in the context of the subscriber tenant
3. Observe failure with "Failed to get destination."

Expected Behavior

tryGetDestination() should successfully resolve the destination. Since the auth type is NoAuthentication, the SDK should not attempt user token exchange. The destination should be returned with its properties so
our code can handle the IAS token fetch separately using the cloudsdk.ias-dependency-name and tokenService.body.url properties.
