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.
説明
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
このコードが表示される場合
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
解決方法
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.
説明
The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
このコードが表示される場合
A transaction or optimistic concurrency check failed — for example, a read-modify-write cycle detected a conflict with another concurrent operation.
解決方法
Retry the entire read-modify-write sequence from the beginning. Implement proper optimistic concurrency control with version tokens or ETags.
主な違い
gRPC 2: An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
gRPC 10: The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
You encounter 2 when the server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
You encounter 10 when a transaction or optimistic concurrency check failed — for example, a read-modify-write cycle detected a conflict with another concurrent operation.

For 2 (UNKNOWN): 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. For 10 (ABORTED): Retry the entire read-modify-write sequence from the beginning. Implement proper optimistic concurrency control with version tokens or ETags.
