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.

Gördüğünüzde
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
Nasıl Düzeltilir
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
Açıklama
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.

The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
Nasıl Düzeltilir
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.
