gRPC 11 OUT_OF_RANGE vs 16 UNAUTHENTICATED
Both gRPC 11 (OUT_OF_RANGE) and 16 (UNAUTHENTICATED) belong to the gRPC Status Codes category. 11 indicates that the operation was attempted past the valid range. For example, seeking or reading past the end of a file. Meanwhile, 16 means that the request does not have valid authentication credentials for the operation.
Description
The operation was attempted past the valid range. For example, seeking or reading past the end of a file.
When You See It
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.
How to Fix
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.
Description
The request does not have valid authentication credentials for the operation.
When You See It
No credentials were provided, or the provided token/certificate is expired or invalid. Different from PERMISSION_DENIED (code 7), which means authenticated but not authorized.
How to Fix
Provide valid authentication credentials (e.g., refresh the OAuth token, regenerate the API key, or renew the client certificate).
