gRPC 1 CANCELLED vs 5 NOT_FOUND
Both gRPC 1 (CANCELLED) and 5 (NOT_FOUND) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 5 means that some requested entity was not found. For example, a file or directory that the RPC was supposed to operate on does not exist.
説明
The operation was cancelled, typically by the caller.
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.

このコードが表示される場合
The resource referenced in the request doesn't exist — such as looking up a user by ID that has been deleted or never created.
解決方法
Verify the resource identifier is correct. Ensure the resource was created before accessing it, or handle the not-found case gracefully in your client.
