gRPC 6 ALREADY_EXISTS vs 12 UNIMPLEMENTED
Both gRPC 6 (ALREADY_EXISTS) and 12 (UNIMPLEMENTED) 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, 12 means that the operation is not implemented or is not supported/enabled in this service.

A create operation failed because a resource with the same unique identifier or name already exists in the system.
Как исправить
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.

The operation is not implemented or is not supported/enabled in this service.
Когда вы это видите
The client called an RPC method that the server does not implement. This often happens when the client uses a newer proto definition than the server supports.

Verify the server version supports the method you're calling. Update the server to implement the missing method, or use an alternative endpoint.
