gRPC 2 UNKNOWN vs 6 ALREADY_EXISTS
Both gRPC 2 (UNKNOWN) and 6 (ALREADY_EXISTS) belong to the gRPC Status Codes category. 2 indicates that an unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code. Meanwhile, 6 means 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.
विवरण
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
जब आप इसे देखें
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
कैसे ठीक करें
Check the server logs for the underlying exception. Wrap server-side errors with explicit gRPC status codes instead of letting them bubble up as UNKNOWN.
विवरण
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.
जब आप इसे देखें
A create operation failed because a resource with the same unique identifier or name already exists in the system.
कैसे ठीक करें
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
