gRPC 1 CANCELLED vs 12 UNIMPLEMENTED
Both gRPC 1 (CANCELLED) and 12 (UNIMPLEMENTED) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 12 means that the operation is not implemented or is not supported/enabled in this service.
描述
The operation was cancelled, typically by the caller.
何时出现
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
如何修复
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
描述
The operation is not implemented or is not supported/enabled in this service.
何时出现
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.
如何修复
Verify the server version supports the method you're calling. Update the server to implement the missing method, or use an alternative endpoint.
