public class InvalidRequestError
extends A2AError

JSON-RPC error indicating that the request payload is not a valid JSON-RPC Request object.

This error is returned when the JSON-RPC request fails structural validation. Common causes include:

• Missing required JSON-RPC fields (jsonrpc, method, id)
• Invalid JSON-RPC version (must be "2.0")
• Malformed request structure
• Type mismatches in required fields

Corresponds to JSON-RPC 2.0 error code -32600.

Usage example:

 // Default error with standard message
 throw new InvalidRequestError();

 // Custom error message
 throw new InvalidRequestError("Missing 'method' field in request");
