gRPC 2 UNKNOWN vs 10 ABORTED
Both gRPC 2 (UNKNOWN) and 10 (ABORTED) belong to the gRPC Status Codes category. 2 indicates 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. Meanwhile, 10 means that the operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
Descripción
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
Cuándo lo verás
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
Cómo solucionarlo
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.
Descripción
The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
Cuándo lo verás
A transaction or optimistic concurrency check failed — for example, a read-modify-write cycle detected a conflict with another concurrent operation.
Cómo solucionarlo
Retry the entire read-modify-write sequence from the beginning. Implement proper optimistic concurrency control with version tokens or ETags.
