gRPC 6 ALREADY_EXISTS vs 15 DATA_LOSS
Both gRPC 6 (ALREADY_EXISTS) and 15 (DATA_LOSS) 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, 15 means that unrecoverable data loss or corruption has occurred.

Cuándo lo verás
A create operation failed because a resource with the same unique identifier or name already exists in the system.
Cómo solucionarlo
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
Descripción
Unrecoverable data loss or corruption has occurred.
Cuándo lo verás
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
