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.
描述
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
何时出现
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.
如何修复
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
描述
Unrecoverable data loss or corruption has occurred.
何时出现
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
如何修复
Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
