gRPC 4 DEADLINE_EXCEEDED vs 12 UNIMPLEMENTED
Both gRPC 4 (DEADLINE_EXCEEDED) and 12 (UNIMPLEMENTED) belong to the gRPC Status Codes category. 4 indicates that the deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. Meanwhile, 12 means that the operation is not implemented or is not supported/enabled in this service.
विवरण
The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.
जब आप इसे देखें
The RPC took longer than the configured deadline allows. Common in slow network conditions, overloaded servers, or when the deadline is set too aggressively.
कैसे ठीक करें
Increase the client deadline, optimize the server-side processing, or add server-side caching. If the operation might have succeeded, check idempotency before retrying.
विवरण
The operation is not implemented or is not supported/enabled in this service.
जब आप इसे देखें
The client called an RPC method that the server does not implement. This often happens when the client uses a newer proto definition than the server supports.
कैसे ठीक करें
Verify the server version supports the method you're calling. Update the server to implement the missing method, or use an alternative endpoint.
