public class InvalidParamsError
extends A2AError

JSON-RPC error indicating that method parameters are invalid or missing required fields.

This error is returned when a JSON-RPC method is called with parameters that fail validation. Common causes include:

• Missing required parameters
• Parameters of incorrect type
• Parameter values outside acceptable ranges
• Malformed parameter structures

Corresponds to JSON-RPC 2.0 error code -32602.

Usage example:

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

 // Custom error message
 throw new InvalidParamsError("taskId parameter is required");
