gRPC 3 INVALID_ARGUMENT vs 14 UNAVAILABLE
Both gRPC 3 (INVALID_ARGUMENT) and 14 (UNAVAILABLE) 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, 14 means that the service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.
الوصف
The client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system.
متى تراه
A request field failed validation — for example, a negative page size, a malformed email, or a required field left empty.

Inspect the request payload and fix the invalid field. Check the API documentation for expected formats and constraints.
الوصف
The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.
متى تراه
The server is overloaded, shutting down, or a network partition occurred. This is the most common code to retry on, as it's explicitly transient.
كيفية الإصلاح
Retry with exponential backoff. If persistent, check the server health, load balancer configuration, and network connectivity between client and server.
