gRPC 2 UNKNOWN vs 11 OUT_OF_RANGE
Both gRPC 2 (UNKNOWN) and 11 (OUT_OF_RANGE) 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, 11 means that the operation was attempted past the valid range. For example, seeking or reading past the end of a file.
คำอธิบาย
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
เมื่อคุณพบเห็น
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
วิธีแก้ไข
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.
คำอธิบาย
The operation was attempted past the valid range. For example, seeking or reading past the end of a file.
เมื่อคุณพบเห็น
A pagination offset exceeded the available data, or an iterator moved past the end of a collection. Unlike INVALID_ARGUMENT, this depends on the current state of the data.
วิธีแก้ไข
Check the valid range before making the request. For pagination, use the total count or next-page token to avoid requesting beyond the last page.
