Record Class JsonRpcError

java.lang.Object
java.lang.Record
dev.tachyonmcp.core.transport.jsonrpc.JsonRpcError
Record Components:
code - the error code
message - a short description of the error
data - optional additional error data
httpStatus - the HTTP status this protocol version ties to this error (200 by default — the JSON-RPC-over-HTTP convention where the transport succeeds even though the RPC failed; protocol versions that tie specific errors to HTTP status codes, e.g. MCP 2026-07-28, set this per error kind)
public record JsonRpcError(int code, String message, @Nullable String data, int httpStatus) extends Record
A JSON-RPC error object, produced by a protocol version's ProtocolResponseMapper.
