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.

The operation was cancelled, typically by the caller.

เมื่อคุณพบเห็น

The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.

วิธีแก้ไข

If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
