gRPC 1 CANCELLED vs 2 UNKNOWN
Both gRPC 1 (CANCELLED) and 2 (UNKNOWN) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 2 means that an unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
Описание
The operation was cancelled, typically by the caller.
Когда вы это видите
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
Как исправить
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
Описание
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
Когда вы это видите
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
Как исправить
Check the server logs for the underlying exception. Wrap server-side errors with explicit gRPC status codes instead of letting them bubble up as UNKNOWN.
