gRPC 3 INVALID_ARGUMENT vs 4 DEADLINE_EXCEEDED
Both gRPC 3 (INVALID_ARGUMENT) and 4 (DEADLINE_EXCEEDED) belong to the gRPC Status Codes category. 3 indicates that the client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system. Meanwhile, 4 means that the deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.
Description
The client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system.
Quand vous le voyez
A request field failed validation — for example, a negative page size, a malformed email, or a required field left empty.
Comment résoudre
Inspect the request payload and fix the invalid field. Check the API documentation for expected formats and constraints.
Description
The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.
Quand vous le voyez
The RPC took longer than the configured deadline allows. Common in slow network conditions, overloaded servers, or when the deadline is set too aggressively.
Comment résoudre
Increase the client deadline, optimize the server-side processing, or add server-side caching. If the operation might have succeeded, check idempotency before retrying.
