gRPC 1 CANCELLED vs 3 INVALID_ARGUMENT
Both gRPC 1 (CANCELLED) and 3 (INVALID_ARGUMENT) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 3 means that the client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system.

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