It seems likely that your code is setting up a voice assistant using Livekit's 
VoicePipelineAgent
with various plugins for VAD, STT, LLM, and TTS. However, there are a few points to consider: 1. Plugin Initialization: Ensure that the plugins (Silero VAD, Deepgram STT, Google LLM, and Cartesia TTS) are correctly initialized with the necessary API keys and configurations. The 
os.getenv
function is used to fetch environment variables, so make sure these are set correctly in your environment. 2. Room Connection: The code attempts to connect to a Livekit room using a URL and token. Ensure that these are valid and that the Livekit server is accessible. 3. Error Handling: The code includes error handling for connection timeouts and other exceptions. Make sure to check the logs for any specific error messages that might indicate what needs to be fixed. 4. Assistant Lifecycle: The 
VoicePipelineAgent
is started and managed within an asynchronous loop. Ensure that the 
start
, 
cleanup
, and 
disconnect
methods are correctly implemented and called. If you need more detailed guidance or encounter specific errors, please let me know!

@millions-hair-24956 I ran the py and got this returned Connecting to room... Timeout waiting for room connection error putting to queue: Event loop is closed error putting to queue: Event loop is closed
g
The error message "Timeout waiting for room connection" indicates that the connection to the Livekit room was not established within the specified timeout period. The subsequent "event loop is closed" errors suggest that the asyncio event loop was closed unexpectedly, possibly due to the timeout or an unhandled exception. Here are a few steps to troubleshoot and resolve the issue: 1. Check Livekit URL and Token: Ensure that the 
LIVEKIT_URL
and 
LIVEKIT_TOKEN
environment variables are correctly set and valid. These are crucial for establishing a connection to the Livekit server. 2. Network Connectivity: Verify that there are no network issues preventing the connection to the Livekit server. This includes checking firewall settings and ensuring that the server is reachable. 3. Increase Timeout: Consider increasing the timeout duration in the 
asyncio.wait_for
call to allow more time for the connection to be established, especially if network latency is a factor. 4. Error Handling: Ensure that any exceptions are properly caught and logged to provide more context on what might be causing the event loop to close. Would you like more detailed guidance on any of these steps?

The error "Timeout waiting for room connection" indicates that the connection to the Livekit room was not established within the specified timeout period. Here are some steps to troubleshoot and resolve the issue: 1. Verify Environment Variables: Ensure that the 
LIVEKIT_URL
and 
LIVEKIT_TOKEN
environment variables are correctly set. These are crucial for establishing a connection to the Livekit server. Double-check that the token is valid and not expired. 2. Network Connectivity: Check for any network issues that might be preventing the connection to the Livekit server. This includes verifying firewall settings and ensuring that the server is reachable from your network. 3. Increase Timeout: Consider increasing the timeout duration in the 
asyncio.wait_for
call to allow more time for the connection to be established, especially if network latency is a factor. 4. Check Server Logs: If you have access to the Livekit server logs, check for any errors or warnings that might indicate why the connection is failing. 5. Debugging: Add more logging to capture detailed information about the connection attempt. This can help identify where the process is failing.

It seems likely that the issue you're encountering is related to the token decoding error: "Error decoding token: module 'jwt' has no attribute 'dumps'". This suggests that there might be a problem with how the JWT token is being handled in your code. Here are some steps to address this: 1. JWT Library: Ensure that you are using the correct JWT library. The error message suggests that there might be a misuse of the 
jwt
library. Typically, JWT tokens are encoded and decoded using 
jwt.encode()
and 
jwt.decode()
, not 
jwt.dumps()
. Verify that your code is using the correct methods for handling JWT tokens. 2. Token Generation: Double-check the process of generating the token. Ensure that the token is correctly signed and includes all necessary claims such as 
room
, 
identity
, and 
permissions
. The token should be a valid JWT string. 3. Environment Variables: Verify that the 
LIVEKIT_TOKEN
environment variable is set correctly and contains a valid JWT token. You can use online JWT decoders to inspect the token and ensure it is correctly formatted. 4. Server Logs: Since the server response status is 200 and the response is OK, it indicates that the server is reachable. However, the token issue might be preventing a successful connection. Check the server logs for any additional error messages related to token validation. Would you like more detailed guidance on any of these steps?

1. @millions-hair-24956 "Can you show me the correct code for token generation and verification for a voice assistant using the latest LiveKit Python SDK? I'm getting JWT errors and connection timeouts." 2. "Here's my current error when running the voice assistant:
Copy code
Connecting to room...
Timeout waiting for room connection
error putting to queue: Event loop is closed
What's the correct way to set up the room connection and event loop for a voice assistant?" 1. "Can you share a complete, working example of a voice assistant using: • Cartesia for TTS • Deepgram for STT • Google Gemini for LLM • Silero for VAD"
g
To address your questions, I'll provide guidance on generating and verifying tokens, setting up a room connection, and a complete example of a voice assistant using the specified plugins. 1. Token Generation and Verification To generate a token for LiveKit, you need to use the 
AccessToken
class from the LiveKit Python SDK. Here's a basic example:
Copy code
from livekit import AccessToken, VideoGrant
import os

def generate_token(room_name, identity):
    api_key = os.getenv('LIVEKIT_API_KEY')
    api_secret = os.getenv('LIVEKIT_API_SECRET')

    if not api_key or not api_secret:
        raise ValueError("API key and secret must be set in environment variables.")

    grant = VideoGrant(room_join=True, room=room_name)
    token = AccessToken(api_key, api_secret, identity=identity)
    token.add_grant(grant)
    return token.to_jwt()

# Example usage
room_name = "example_room"
identity = "user123"
token = generate_token(room_name, identity)
print("Generated Token:", token)
2. Setting Up Room Connection and Event Loop Ensure that your event loop is correctly set up and that the room connection is properly handled. Here's a basic setup:
Copy code
import asyncio
from livekit import rtc

async def connect_to_room(url, token):
    room = rtc.Room()

    @room.on("connected")
    def on_connected():
        print("Connected to room")

    @room.on("disconnected")
    def on_disconnected():
        print("Disconnected from room")

    await room.connect(url, token)
    return room

async def main():
    url = os.getenv('LIVEKIT_URL')
    token = os.getenv('LIVEKIT_TOKEN')

    if not url or not token:
        raise ValueError("LiveKit URL and token must be set in environment variables.")

    room = await connect_to_room(url, token)

    try:
        while True:
            await asyncio.sleep(1)
    except KeyboardInterrupt:
        print("Shutting down...")
    finally:
        await room.disconnect()

if __name__ == "__main__":
    asyncio.run(main())
3. Complete Voice Assistant Example Here's a complete example using the specified plugins:
Copy code
import os
import asyncio
from dotenv import load_dotenv
from livekit.plugins import cartesia, deepgram, google, silero
from livekit.agents.pipeline import VoicePipelineAgent
from livekit import rtc

# Load environment variables
load_dotenv()

async def main():
    # Initialize plugins
    vad = silero.VAD.load()
    stt = deepgram.STT()
    llm = google.LLM(
        model="gemini-pro",
        api_key=os.getenv('GOOGLE_API_KEY')
    )
    tts = cartesia.TTS(
        model="sonic-english",
        voice="c2ac25f9-ecc4-4f56-9095-651354df60c0",
        speed=0.8,
        emotion=["curiosity:highest", "positivity:high"]
    )

    # Create room with event handling
    room = rtc.Room()
    connection_ready = asyncio.Event()

    @room.on("connected")
    def on_connected():
        print("Room connection established")
        connection_ready.set()

    @room.on("disconnected")
    def on_disconnected():
        print("Room disconnected")
        connection_ready.clear()

    print("Connecting to room...")
    await room.connect(
        url=os.getenv('LIVEKIT_URL'),
        token=os.getenv('LIVEKIT_TOKEN')
    )

    # Wait for connection to be ready
    try:
        await asyncio.wait_for(connection_ready.wait(), timeout=10.0)
        print(f"Connected to room: {room.name}")

        # Create and start voice assistant
        assistant = VoicePipelineAgent(
            vad=vad,
            stt=stt,
            llm=llm,
            tts=tts
        )

        print("Starting voice assistant...")
        await assistant.start(room)
        print("Assistant started successfully")

        # Keep the connection alive
        while True:
            if not connection_ready.is_set():
                print("Connection lost!")
                break
            await asyncio.sleep(1)

    except asyncio.TimeoutError:
        print("Timeout waiting for room connection")
    except KeyboardInterrupt:
        print("\nShutting down...")
    except Exception as e:
        print(f"Error: {e}")
    finally:
        if hasattr(assistant, 'cleanup'):
            await assistant.cleanup()
        elif hasattr(assistant, 'close'):
            await assistant.close()

        if room and hasattr(room, 'disconnect'):
            await room.disconnect()
        print("Cleanup completed")

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        print("\nInterrupted by user")
    except Exception as e:
        print(f"Fatal error: {e}")

g
The error message "HTTP error: 401 Unauthorized" indicates that the token used to connect to the LiveKit room is not authorized. This can be caused by several issues related to the token or its configuration: 1. Invalid Token: The token might be incorrectly generated or malformed. Ensure that the token is a valid JWT and includes all necessary claims such as 
room
, 
identity
, and 
permissions
. 2. Incorrect API Key/Secret: Double-check that the API key and secret used to generate the token are correct and match those configured on your LiveKit server. 3. Token Expiration: Ensure that the token has not expired. Tokens typically have an expiration time, and if the token is expired, the server will reject it. 4. Permissions: Verify that the token includes the correct permissions for the room you are trying to access. The token should have a 
VideoGrant
with 
roomJoin
set to 
true
and the correct 
room
specified. 5. Room Name: Ensure that the room name specified in the token matches the room you are trying to connect to. Any mismatch will result in a 401 error. 6. Server Configuration: Check the server configuration to ensure that it is set up to accept connections with the provided token. Would you like more detailed guidance on any of these steps?

used in the token generation match exactly with what you are trying to connect to. Any mismatch will result in a 401 error. - Verify that the 
VideoGrants
are correctly set. The 
room_join
permission should be 
True
, and the 
room
should match the room you are connecting to. 2. Token Format: - Ensure that the token is correctly formatted as a JWT. The 
token.to_jwt()
method should be used to generate the JWT string. In your code, it seems like there might be a formatting issue with 
<http://token.to|token.to>_jwt()
. It should be 
token.to_jwt()
. 3. Environment Variables: - Double-check that the 
LIVEKIT_API_KEY
, 
LIVEKIT_API_SECRET
, 
LIVEKIT_URL
, and 
LIVEKIT_TOKEN
environment variables are correctly set and match the configuration on your LiveKit server. 4. Token Verification: - When decoding the token for verification, ensure that you are using the correct library and method. The 
jwt.decode()
function should be used with the 
options={"verify_signature": False}
parameter for debugging purposes only. 5. Server Configuration: - Ensure that the LiveKit server is configured to accept connections with the provided token. Check the server logs for any additional error messages related to token validation. Here's a corrected version of the token generation code:
Copy code
# token_generator.py
from livekit import api

        raise ValueError("API key and secret must be set in environment variables.")

    # Create token
    token = api.AccessToken(api_key, api_secret)

    # Set identity and name
    token.identity = identity
    token.name = "RoleShape AI Assistant"

    # Set video grants
    token.grants = api.VideoGrants(
        room=room_name,
        room_join=True,
        can_publish=True,
        can_subscribe=True,
        can_publish_data=True
    )

    return token.to_jwt()

if __name__ == "__main__":
    try:
        # Generate token
        room_name = "roleshape-room"
        identity = "roleshape-assistant"
        token = generate_token(room_name, identity)

        print("\nGenerated Token:")
        print(token)

        # Verify token contents
        import jwt
        decoded = jwt.decode(token, options={"verify_signature": False})
        print("\nToken contents:")
        for key, value in decoded.items():
            print(f"{key}: {value}")

    except Exception as e:
        print(f"Error: {e}")
Make sure to replace any placeholders with actual values and verify that the token is correctly generated and used in your application.

g
The "401 Unauthorized" error indicates that the token used to connect to the LiveKit room is not valid or lacks the necessary permissions. Here are some steps to troubleshoot and resolve the issue: 1. Token Verification: - Ensure that the token is correctly generated with the necessary permissions. The token should include a 
VideoGrant
with 
roomJoin
set to 
True
and the correct 
room
specified. - Verify that the token is a valid JWT and is not expired. You can use a JWT decoder to inspect the token and ensure it contains the expected claims. 2. API Key and Secret: - Double-check that the API key and secret used to generate the token are correct and match those configured on your LiveKit server. 3. Room Name and Identity: - Ensure that the 
room_name
and 
identity
used in the token generation match exactly with what you are trying to connect to. Any mismatch will result in a 401 error. 4. Environment Variables: - Verify that the 
LIVEKIT_API_KEY
, 
LIVEKIT_API_SECRET
, 
LIVEKIT_URL
, and 
LIVEKIT_TOKEN
environment variables are correctly set and match the configuration on your LiveKit server. 5. Server Configuration: - Check the server configuration to ensure that it is set up to accept connections with the provided token. Review the server logs for any additional error messages related to token validation. If you have verified all the above and the issue persists, consider regenerating the token and ensuring all parameters are correctly set. Would you like more detailed guidance on any of these steps?

It seems likely that the issue with the token not containing video grants is due to how the token is being generated and the grants are being set. Let's address the key points: 1. Token Generation: - Ensure that the 
VideoGrant
is correctly set when generating the token. The 
api.AccessToken
class should be used to add the 
VideoGrant
with the necessary permissions. 2. Correct Method Usage: - The method 
token.to_jwt()
should be used to convert the token to a JWT string. It seems there might be a formatting issue with 
<http://token.to|token.to>_jwt()
. It should be 
token.to_jwt()
. 3. Setting Video Grants: - Use the 
VideoGrant
class to set the video permissions explicitly. Here's how you can modify your token generation code:
Copy code
# token_generator.py
from livekit import api
import os
from dotenv import load_dotenv

load_dotenv()

def generate_token(room_name, identity):
    api_key = os.getenv('LIVEKIT_API_KEY')
    api_secret = os.getenv('LIVEKIT_API_SECRET')

    if not api_key or not api_secret:
        raise ValueError("API key and secret must be set in environment variables.")

    # Create token
    token = api.AccessToken(api_key, api_secret)

    # Set identity and name
    token.identity = identity
    token.name = "RoleShape AI Assistant"

    # Set video grants
    video_grant = api.VideoGrant(
        room=room_name,
        room_join=True,
        can_publish=True,
        can_subscribe=True,
        can_publish_data=True
    )
    token.add_grant(video_grant)

    return token.to_jwt()

if __name__ == "__main__":
    try:
        # Generate token
        room_name = "roleshape-room"
        identity = "roleshape-assistant"
        token = generate_token(room_name, identity)

        print("\nGenerated Token:")
        print(token)

        # Verify token contents
        import jwt
        decoded = jwt.decode(token, options={"verify_signature": False})
        print("\nToken contents:")
        for key, value in decoded.items():
            print(f"{key}: {value}")

    except Exception as e:
        print(f"Error: {e}")
4. Verification: - After generating the token, use a JWT decoder to verify that the token contains the expected video grants and other claims. By ensuring the correct usage of the 
VideoGrant
class and the 
to_jwt()
method, you should be able to generate a token with the necessary video permissions. Sources: - LiveKit Authentication 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

g
To connect using the web interface after setting up your LiveKit agent, you need to follow these steps: 1. Generate a Token: Ensure you have a valid token for the room you want to connect to. This token should be generated with the necessary permissions (e.g., room join, publish, subscribe). You can use the token generation script you have or the LiveKit CLI to create this token. 2. Set Up a Web Interface: You can use a sample web application provided by LiveKit or create your own using the LiveKit JavaScript SDK. Here's a basic outline of how to set up a web interface: - Install LiveKit Client SDK: If you haven't already, install the LiveKit client SDK in your web project.
Copy code
npm install livekit-client
- Create a Simple Web Page: Set up a basic HTML page with a script to connect to the LiveKit room using the token.

3. Run the Web Interface: Open the HTML file in a web browser. Ensure that the 
url
and 
token
variables are set to your LiveKit server URL and the generated token, respectively. 4. Test the Connection: Once the web interface is running, it should connect to the LiveKit room using the provided token. You should see video and audio streams if everything is set up correctly. By following these steps, you should be able to connect to your LiveKit room using a web interface. If you encounter any issues, ensure that the token is valid and that the server URL is correct.

i created a test client.

Error: bad argument type for built-in operation (venv) Roleshape@MacBookPro roleshape-voice-new % @millions-hair-24956

The error "bad argument type for built-in operation" suggests that there might be an issue with the types of arguments being passed to a function or method in your code. Here are a few steps to troubleshoot and resolve the issue: 1. Check Environment Variables: Ensure that the 
LIVEKIT_URL
and 
LIVEKIT_CLIENT_TOKEN
environment variables are correctly set. If they are not set or are empty, the 
os.getenv()
function will return 
None
, which could lead to type errors. 2. Logging Setup: The line 
logging.basicConfig(level=<http://logging.INFO|logging.INFO>)
seems to have an incorrect syntax. It should be 
logging.basicConfig(level=logging.INFO)
without the angle brackets and URL-like syntax. 3. Token and URL: Verify that the token and URL are valid strings. If either is 
None
or an incorrect type, it could cause the error. 4. Debugging: Add print statements to check the values of 
url
and 
token
before the 
room.connect()
call to ensure they are correctly set. Here's a revised version of your code with these considerations:
Copy code
# test_client.py
import asyncio
from livekit import rtc
import os
from dotenv import load_dotenv
import logging

# Set up logging
logging.basicConfig(level=logging.INFO)

load_dotenv()

async def main():
    room = rtc.Room()

    @room.on("connected")
    def on_connected():
        print("\n:large_green_circle: Connected to room!")
        if hasattr(room, 'local_participant'):
            print(f"Connected as: {room.local_participant.identity}")

    @room.on("participant_connected")
    def on_participant_connected(participant):
        print(f":bust_in_silhouette: Participant joined: {participant.identity}")

    @room.on("track_subscribed")
    def on_track_subscribed(track, publication, participant):
        print(f":microphone: Subscribed to {track.kind} track from {participant.identity}")

    # Retrieve environment variables
    url = os.getenv('LIVEKIT_URL')
    token = os.getenv('LIVEKIT_CLIENT_TOKEN')

    # Debugging: Print URL and token
    print(f"URL: {url}")
    print(f"Token: {token}")

    print("\nConnecting to room...")
    await room.connect(url=url, token=token)

    print("\nConnected! You can now speak to the assistant.")
    print("Press Ctrl+C to exit")

    try:
        while True:
            await asyncio.sleep(1)
    except KeyboardInterrupt:
        print("\nDisconnecting...")
    finally:
        await room.disconnect()
        print("Disconnected")

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        print("\nInterrupted by user")
    except Exception as e:
        print(f"Error: {e}")
By ensuring that the environment variables are correctly set and the logging setup is correct, you should be able to resolve the error. If the issue persists, please let me know!
