gRPC 0 OK vs 14 UNAVAILABLE
Both gRPC 0 (OK) and 14 (UNAVAILABLE) belong to the gRPC Status Codes category. 0 indicates that the operation completed successfully. Not an error; returned on success. Meanwhile, 14 means that the service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.

このコードが表示される場合
The server is overloaded, shutting down, or a network partition occurred. This is the most common code to retry on, as it's explicitly transient.
解決方法
Retry with exponential backoff. If persistent, check the server health, load balancer configuration, and network connectivity between client and server.
