gRPC 7 PERMISSION_DENIED vs 15 DATA_LOSS
Both gRPC 7 (PERMISSION_DENIED) and 15 (DATA_LOSS) belong to the gRPC Status Codes category. 7 indicates that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead. Meanwhile, 15 means that unrecoverable data loss or corruption has occurred.
説明
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
このコードが表示される場合
The authenticated user lacks the required role, scope, or policy to perform this action. Different from UNAUTHENTICATED (code 16), which means no credentials at all.
解決方法
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
説明
Unrecoverable data loss or corruption has occurred.
このコードが表示される場合
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
解決方法
Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
