gRPC 6 ALREADY_EXISTS vs 13 INTERNAL
Both gRPC 6 (ALREADY_EXISTS) and 13 (INTERNAL) 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, 13 means that an internal error occurred. This means that some invariant expected by the underlying system has been broken.
説明
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.
このコードが表示される場合
A create operation failed because a resource with the same unique identifier or name already exists in the system.
解決方法
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
説明
An internal error occurred. This means that some invariant expected by the underlying system has been broken.
このコードが表示される場合
A server-side bug, a corrupted internal state, or an unexpected failure in a dependency. This is the gRPC equivalent of HTTP 500.
解決方法
Check the server error logs and traces for the root cause. This typically indicates a bug that needs to be fixed in the server code.
