このコードが表示される場合

The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.

解決方法

If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.

説明

The operation is not implemented or is not supported/enabled in this service.

このコードが表示される場合

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.
