gRPC 1 CANCELLED vs 4 DEADLINE_EXCEEDED
Both gRPC 1 (CANCELLED) and 4 (DEADLINE_EXCEEDED) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 4 means that the deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.

The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.
Wann Sie es sehen
The RPC took longer than the configured deadline allows. Common in slow network conditions, overloaded servers, or when the deadline is set too aggressively.
Wie man es behebt
Increase the client deadline, optimize the server-side processing, or add server-side caching. If the operation might have succeeded, check idempotency before retrying.
