how do i clear all message items from a realtime session?
g
It seems likely that you can clear message items from a 
RealtimeSession
by using the 
delete
method on 
ConversationItem
. This method allows you to delete specific conversation items by their 
item_id
. However, there is no direct method mentioned in the data sources to clear all message items at once. Would you like more details on how to use the 
delete
method for individual items? Sources: - RealtimeSession 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

how do i track item_ids as they're created?
@millions-hair-24956
g
To track `item_id`s as they are created in a 
RealtimeSession
, you can listen for the 
conversation.item.created
event. This event provides details about newly created conversation items, including their 
item_id
. You can handle this event to store or log the `item_id`s as they are generated. Would you like more details on setting up event listeners for this purpose? Sources: - ServerEvent 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

show me how i'd do this in python
@millions-hair-24956

To track `item_id`s as they are created in a 
RealtimeSession
using Python, you can set up an event listener for the 
conversation.item.created
event. Here's a basic example of how you might implement this:
Copy code
import asyncio
from livekit.plugins.openai.realtime import RealtimeSession
from livekit.plugins.openai.realtime.api_proto import ServerEvent

async def track_item_ids(session: RealtimeSession):
    @session.on("conversation.item.created")
    def on_item_created(event: ServerEvent.ConversationItemCreated):
        item_id = event.item["id"]
        print(f"Item created with ID: {item_id}")

# Example usage
async def main():
    session = RealtimeSession(...)  # Initialize your session with necessary parameters
    await track_item_ids(session)
    # Continue with other session operations

asyncio.run(main())
This code sets up an event listener that prints the 
item_id
of each newly created conversation item. You need to replace the 
RealtimeSession(...)
with the actual initialization of your session. Would you like more details or help with a specific part of this setup? Sources: - RealtimeSession - ServerEvent 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

            item_id = event.item["id"]
            asyncio.create_task(
                send_debug_log(
                    self.ctx,
                    "SYSTEM",
                    f"Item created with ID: {item_id}"
                )
            )
            print(f"Item created with ID: {item_id}")
            self.conversation_item_ids.append(item_id)

The 
conversation.item.created
event should be available as per the ServerEvent documentation. If you're not seeing this event, ensure that your event listener is correctly set up and that the session is properly initialized and running. Here are a few things to check: 1. Session Initialization: Ensure that your 
RealtimeSession
is correctly initialized and connected. The session must be active for events to be emitted. 2. Event Listener Registration: Verify that the event listener is registered before any conversation items are created. This ensures that you don't miss any events. 3. Correct Event Type: Double-check that the event type is correctly specified as 
"conversation.item.created"
. 4. Debugging: Add logging or print statements to confirm that the session is running and that the event listener is active. If these checks don't resolve the issue, you might want to verify that the version of the LiveKit library you are using supports this event, as there might be discrepancies in documentation or implementation.

I know there's a session because it's talking to me, but my listener isn't logging anything @millions-hair-24956
g
If your session is active and interacting with you, but the listener isn't logging anything, consider the following troubleshooting steps: 1. Ensure Event Emission: Confirm that the 
conversation.item.created
event is actually being emitted. You can do this by checking if other events are being logged or by adding a temporary listener for a different event to verify that the event system is working. 2. Listener Registration: Make sure the listener is registered before any conversation items are created. If the listener is registered after the items are created, it won't catch those events. 3. Correct Event Handling: Double-check that the event handler function is correctly defined and that there are no syntax errors or exceptions preventing it from executing. You can add a simple print statement at the start of the handler to verify that it's being called. 4. Logging Configuration: Ensure that your logging configuration is set up to display or record the logs. If you're using a logging library, check that the log level is set to capture debug or info messages. 5. Session and Agent Initialization: Verify that the 
RealtimeSession
and agent are correctly initialized and that the session is not being reset or reinitialized elsewhere in your code, which might unregister the listener. If these steps don't resolve the issue, you might want to add more detailed logging or debugging to trace the flow of events and confirm that the listener is correctly set up and active.

g
If neither the 
conversation.item.created
nor the 
response.created
events are logging, consider these troubleshooting steps: 1. Event Listener Registration: Ensure that the event listeners are registered immediately after the session is initialized and before any conversation items or responses are created. This ensures that the listeners are active when the events are emitted. 2. Correct Event Types: Double-check that the event types are correctly specified. The event names should match exactly as defined in the documentation. 3. Session Initialization: Verify that the 
session
object is correctly initialized and that it is the same session object that is being used to create conversation items and responses. 4. Debugging: Add print statements or logging at the start of your script to confirm that the session is initialized and that the event listeners are being registered. This can help ensure that the setup is correct. 5. Check for Exceptions: Ensure that there are no exceptions or errors in the event handler functions that might prevent them from executing. You can add try-except blocks to catch and log any exceptions. 6. Logging Configuration: Make sure your logging configuration is set to display or record the logs. If you're using a logging library, check that the log level is set to capture debug or info messages. If these steps don't resolve the issue, you might want to add more detailed logging or debugging to trace the flow of events and confirm that the listeners are correctly set up and active.

yeah i'm doing it right after the session is created and then having a back and forth convo and nothing is logging here..
@millions-hair-24956
g
It seems likely that the issue might be related to how the event listeners are being registered or how the session is being managed. Here are a few additional steps you can take to troubleshoot: 1. Verify Event Emission: Ensure that the events are actually being emitted by adding temporary print statements or logging in the methods that create conversation items and responses. This will confirm that the events are being triggered. 2. Check for Multiple Sessions: Ensure that there is only one active session and that the event listeners are registered to the correct session object. If there are multiple sessions, the listeners might be attached to a different session than the one being used for the conversation. 3. Use Debugging Tools: Utilize debugging tools or breakpoints to step through the code and verify that the event listeners are being registered and that the session is active. 4. Simplify the Setup: Temporarily simplify your setup by removing other components or logic to isolate the issue. This can help identify if there is a specific part of the code causing the problem. 5. Review Documentation: Double-check the documentation to ensure that the event types and listener registration methods are being used correctly. If these steps don't resolve the issue, you might want to consider reaching out to the LiveKit community or support for further assistance.

is there maybe another event i should be listening to on the session or agent?
@millions-hair-24956
g
If the 
conversation.item.created
and 
response.created
events are not working, you might consider listening to other related events to diagnose the issue or gather the information you need. Here are some alternative events you can listen to: 1. 
response.output_item.added
: This event is triggered when a new output item is added to a response. It can help you track when responses are being processed. 2. 
response.done
: This event indicates that a response has been fully processed. It can be useful to confirm that the response cycle is completing. 3. 
input_audio_buffer.speech_committed
: This event is triggered when speech input is committed, which might help in tracking user inputs. 4. 
input_audio_buffer.speech_started
and 
input_audio_buffer.speech_stopped
: These events can help track when speech input begins and ends, providing insight into the interaction flow. 5. 
session.created
: This event confirms the creation of a session, ensuring that your session setup is correct. Make sure to register these listeners immediately after initializing the session to ensure they capture the events. If these events still do not log, it might indicate a deeper issue with the session or event handling setup. Would you like more detailed guidance on setting up listeners for these events?

If your code is not logging the 
conversation.item.created
event despite the session being active, consider the following steps to troubleshoot: 1. Verify Event Emission: Ensure that the 
conversation.item.created
event is actually being emitted. You can do this by adding logging or print statements in the code where conversation items are created to confirm that this part of the code is being executed. 2. Check Event Listener Registration: Make sure the event listener is registered immediately after the session is initialized and before any conversation items are created. This ensures that the listener is active when the events are emitted. 3. Correct Event Type: Double-check that the event type is correctly specified as 
"conversation.item.created"
. Any typos or mismatches will prevent the listener from being triggered. 4. Debugging: Add print statements or logging at the start of your script to confirm that the session is initialized and that the event listeners are being registered. This can help ensure that the setup is correct. 5. Check for Exceptions: Ensure that there are no exceptions or errors in the event handler function that might prevent it from executing. You can add try-except blocks to catch and log any exceptions. 6. Logging Configuration: Ensure that your logging configuration is set up to display or record the logs.

It seems likely that the 
_handle_conversation_item_created
method in your code is responsible for processing newly created conversation items, but it does not explicitly emit an event like 
conversation.item.created
. Instead, it processes the item and logs a debug message indicating that a conversation item was created. If you want to emit an event when a conversation item is created, you might need to add an 
emit
call within the 
_handle_conversation_item_created
method. Here's an example of how you could modify the method to emit an event:

                content = cast(api_proto.InputTextContent, content)
                message.content = content["text"]
            elif content["type"] == "input_audio" and content.get("audio"):

            tool_call_id=item["call_id"],

        )

    else:

The error message indicates that there is an 
AttributeError
because the code is trying to access 
event.item["id"]
, but 
event
is a dictionary, not an object with an 
item
attribute. Instead, you should access the dictionary directly using the correct key. Here's how you can modify the event handler to correctly access the `item_id`:
Copy code
@session.on("conversation.item.created")
def on_item_created(event: dict):
    # Access the item_id directly from the event dictionary
    item_id = event["item"]["id"]
    print(f"Item created with ID: {item_id}")
    asyncio.create_task(
        send_debug_log(
            _ctx_,
            "SYSTEM",
            f"Item created with ID: {item_id}"
        )
    )
In this corrected version, 
event["item"]["id"]
is used to access the 
item_id
directly from the dictionary structure of the event. Would you like more detailed guidance on implementing this change?
