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.
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.
Описание
The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
Когда вы это видите
A transaction or optimistic concurrency check failed — for example, a read-modify-write cycle detected a conflict with another concurrent operation.
Как исправить
Retry the entire read-modify-write sequence from the beginning. Implement proper optimistic concurrency control with version tokens or ETags.
