gRPC 1 CANCELLED vs 6 ALREADY_EXISTS
Both gRPC 1 (CANCELLED) and 6 (ALREADY_EXISTS) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. 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.
Descripción
The operation was cancelled, typically by the caller.
Cuándo lo verás
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
Cómo solucionarlo
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
Descripción
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.
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.
