gRPC 6 ALREADY_EXISTS vs 11 OUT_OF_RANGE
Both gRPC 6 (ALREADY_EXISTS) and 11 (OUT_OF_RANGE) belong to the gRPC Status Codes category. 6 indicates that the entity that a client attempted to create already exists. For example, a file or directory that the RPC was supposed to create already exists. Meanwhile, 11 means that the operation was attempted past the valid range. For example, seeking or reading past the end of a file.
설명
The entity that a client attempted to create already exists. For example, a file or directory that the RPC was supposed to create already exists.
이 코드를 보게 되는 경우
A create operation failed because a resource with the same unique identifier or name already exists in the system.
해결 방법
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
설명
The operation was attempted past the valid range. For example, seeking or reading past the end of a file.
이 코드를 보게 되는 경우
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.
해결 방법
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.
