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.
الوصف
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
متى تراه
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
كيفية الإصلاح
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.
الوصف
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.
متى تراه
A create operation failed because a resource with the same unique identifier or name already exists in the system.
كيفية الإصلاح
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
