public class PushNotificationNotSupportedError
extends A2AProtocolError

A2A Protocol error indicating that the agent does not support push notifications.

This error is returned when a client attempts push notification operations on an agent that has AgentCapabilities.pushNotifications() set to false.

Push notifications allow agents to proactively send task updates to clients via HTTP callbacks. Agents that don't support this capability will return this error for all push notification-related methods.

Corresponds to A2A-specific error code -32003.

Usage example:

 if (!agentCard.capabilities().pushNotifications()) {
     throw new PushNotificationNotSupportedError();
 }
