Question

What is the primary indicator in JSON-RPC traffic that a request has failed to reach the server interface versus the model failing to generate a valid call?

Accepted Answer

The primary indicator that a request failed to reach the server interface is the absence of an HTTP response from the server, typically resulting in a transport-level error such as a connection timeout, a connection refused error, or a TCP socket reset before the application layer can process the request. In this scenario, the client never receives a valid JSON-RPC message because the network path or the server process is unavailable. Conversely, if the model fails to generate a valid call or the server interface rejects the request, the server will successfully receive the packet and return a JSON-RPC error object containing a specific error code and message. A JSON-RPC error response is a valid JSON document containing the version, an identifier, and an error object that includes a code, a message, and optional data. If a client receives any valid JSON-RPC formatted error response, it proves the request reached the interface and was parsed by the server. If the client receives no data or a non-JSON transport error, the request never reached the functional server interface.
