before_agent_callback is not working as expected #1567
Description
A simple agent with defined 'before_agent_callback' which is returning 'None' is terminating the session.
Expected as per docs is that returning None should not bypass LLM and work as usual.
Code:
before_agent_callback:
def log_agent_timing(callback_context: CallbackContext) -> Optional[types.Content]:
agent_name = callback_context.agent_name
reqId = callback_context.state[REQUEST_ID]
print(f"{reqId} [Callback] Before Agent call for agent: {agent_name}")
events = callback_context.state["events"]
events.append({"event-name": "before-agent-event", "time": datetime.now().strftime("%Y-%m-%d %H:%M:%S"), "name": agent_name})
callback_context.state["events"] = events
return None
Let me know what else detail is required.
