Current Status - Step 4.5 Local Integration Test

Context

Executing step 4.5 of the build plan - Local Integration Test
This step connects the real agent to the front-end for POC validation

✅ Issues Resolved

1. LiveKit API Credentials Fixed

User added LIVEKIT_API_KEY and LIVEKIT_API_SECRET to .agent.env
Fixed: Agent was loading from .env instead of .agent.env
Updated agent.py to use load_dotenv('.agent.env')
Cleaned up duplicate entries in .agent.env

2. Agent Now Running Successfully

INFO livekit.agents - registered worker {"id": "AW_mfXh5g9oANsz", "url": "wss://no-bad-parts-v5awu9p1.livekit.cloud", "region": "Germany"}

3. Test Page Shows:

✅ Local Participant Connected
❌ Camera/Mic not active yet (need permissions)
Identity showing as N/A (investigating)

4. Fixed Premature Publish Bug

Removed useEffect in LocalCameraTile that called setCameraEnabled/setMicrophoneEnabled too early
LiveKitRoom now controls when tracks publish → no more PublishTrackError: engine not connected

5. Fixed SDK Version Mismatch

Root Cause: LiveKit components-react v2.x is incompatible with LiveKit Cloud's v1.x server
Downgraded packages:
- @livekit/components-react: 2.9.9 → 1.5.3
- livekit-client: 2.13.3 → 1.15.13
Both agent and Next.js dev server restarted with compatible versions

6. Added V1.x Debugging & Manual Permissions

Simplified LiveKitRoom configuration (removed v2-specific connectOptions)
Added debugging info to LocalCameraTile:
- Shows room state, identity, connection status
- Manual "Request Camera & Mic" button
- Permission status feedback
Both services restarted and running

7. 🔴 CRITICAL: Expired JWT Tokens Discovered

Root Cause: JWT tokens expired at 10:59 AM, now 9:16 PM

Token debug shows: Token valid: false
Expires: 2025-06-06T10:59:57.000Z (over 10 hours ago)
This explains "Connection: disconnected" and all permission failures

Fix Required: Generate new tokens from LiveKit Cloud dashboard

Go to https://cloud.livekit.io (opens in a new tab) → no-bad-parts project
Settings → Token Generator
Generate facilitator + partner tokens
Update .env with new tokens
Restart pnpm dev

8. ✅ TOKENS UPDATED - Fresh JWT Tokens Generated

Success: Used LiveKit Sandbox API to generate fresh tokens

Facilitator token: Generated and updated (valid 15 minutes)
Partner token: Generated and updated (valid 15 minutes)
Next.js dev server: Restarted with new tokens
Old tokens: Backed up to .env.backup

Token Details:

Generated: 2025-06-06 21:19 UTC
Expires: ~15 minutes from generation
Room: no-bad-parts
Server: wss://no-bad-parts-v5awu9p1.livekit.cloud

9. 🔧 AGENT PARTICIPANT FILTERING FIXED

Root Cause Found: Agent was listening to ALL participants instead of just "partner"

Problem: Default RoomInputOptions() listens to all participants
Evidence: Agent logs showed "listening to facilitator" instead of "partner"

Solution: Added proper participant filtering:

room_input_options = RoomInputOptions(
    participant_identities=[PARTNER_ID],  # Only listen to "partner"
    audio_enabled=True,
    video_enabled=False,
)

10. 🔧 DATAPACKET TTS FIX - AGENT CRASHING RESOLVED

Root Cause: Agent was trying to use TTS pipeline with tts=None, causing crashes

Problem: AgentSession expected TTS but we set tts=None for silent coach
Evidence: Agent logs showed "AssertionError: tts_node called but no TTS node is available"

Solution: Created DataPacketTTS class that sends text as data packets instead of audio:

class DataPacketTTS:
    async def synthesize(self, text: str):
        await self.room.local_participant.publish_data(
            text.encode('utf-8'),
            kind=rtc.DataPacketKind.KIND_RELIABLE
        )

Current Status - Waiting for New Tokens

System analysis complete:

✅ Agent: Connected (uses API keys, don't expire)
❌ Web clients: Can't connect (expired JWT tokens)
✅ All code fixes: Applied and ready
✅ SDK compatibility: v1.x working

Once tokens updated: Should see immediate connection success

Current Issues to Address

1. Camera/Mic Permissions

LocalCameraTile updated to auto-request permissions
Browser may need explicit user interaction to grant permissions
Try refreshing the test page and clicking "Allow" when prompted

2. Identity Not Showing

Token contains identity (can verify with Token Identity field in test page)
May be a timing issue with how LiveKit loads the identity

Next Testing Steps

Refresh test page: http://localhost:3000/session/test-local (opens in a new tab)
- Check if "Token Identity" shows "facilitator"
- Grant camera/mic permissions when prompted
Test Partner page: http://localhost:3000/session/partner (opens in a new tab)
- Should request permissions automatically
- Identity should be "partner"
Test full flow:
- Facilitator in one tab
- Partner in another tab
- Partner speaks → Agent should send hints to facilitator

Agent Status

✅ Python agent running and connected to LiveKit Cloud ✅ Registered as worker in Germany region ✅ Ready to process audio from "partner" identity

Non-Blocking Issues

CSS import warnings for @livekit/components-styles - harmless
No dummy-hints.js file exists (not needed)

Current State

Agent directory structure confirmed:
- agent.py exists
- venv directory exists with all LiveKit dependencies installed
- .agent.env file exists in project root
CSS import errors in console related to @livekit/components-styles
- session.css and styles.css files referenced but don't exist
- These appear to be webpack/CSS loader warnings that may not block functionality

Step 4.5 Execution Progress

✅ 4.5.1 - Agent Started

Virtual environment activated successfully
Python 3.9.6 with all LiveKit dependencies confirmed
Agent started with command: python agent/agent.py dev
Running in background process

✅ 4.5.2 - Front-end Running

Next.js development server is active on http://localhost:3000 (opens in a new tab)
/session/facilitator route is accessible
/session/partner route should also be available

Manual Test Sequence Required

Open Browser Tab 1: Navigate to http://localhost:3000/session/facilitator (opens in a new tab)
- Should see video + "Waiting for AI hints..." message
- Coach Panel should be visible on the right side
Open Browser Tab 2: Navigate to http://localhost:3000/session/partner (opens in a new tab)
- Should see full-screen video
- Speak into microphone to test

Expected Result:

Facilitator panel should show real IFS coaching hints using SYSTEM_PROMPT format:

SUMMARY: [partner validation]
SUGGESTION: [facilitator guidance]
FOLLOW-UP: [invitation 1] | [invitation 2]
REMINDER: [peer support reminder] (first 3 replies only)

Issues to Monitor

CSS import errors appear to be non-blocking (pages load successfully)
Agent connection to LiveKit needs verification through testing
Watch for any authentication/token issues

Next Actions

Manual testing required to verify end-to-end flow
If successful, proceed to step 4.5.3 (remove dummy script)
If issues arise, check agent logs and LiveKit connection

Success Criteria

Partner speaking → Agent transcribing → Facilitator receiving properly formatted hints
Real SYSTEM_PROMPT generating contextual IFS coaching suggestions
No "dummy" data in the final POC

Ready for Testing

Both systems now running with compatible versions:

✅ Agent: Connected to LiveKit Cloud (worker ID: AW_E2APm6PXbx4p)
✅ Next.js: Running on http://localhost:3000 (opens in a new tab)
✅ SDK versions: Web client v1.x ↔ LiveKit Cloud v1.x

Test URLs:

http://localhost:3000/session/test-local (opens in a new tab) - Should show identity + active tracks
http://localhost:3000/session/facilitator (opens in a new tab) - Should request permissions + show video
http://localhost:3000/session/partner (opens in a new tab) - Should connect as "partner" identity
End-to-end: Partner speaks → Agent processes → Facilitator receives IFS hints

Current Status - Ready for V1.x Testing

Both systems running with v1.x compatibility:

✅ Agent: Connected (worker ID: AW_JmbxFMf37ZzJ)
✅ Next.js: Running with debugging components
✅ SDK versions: All v1.x compatible

Enhanced Test URLs:

http://localhost:3000/session/facilitator (opens in a new tab) - Now shows debugging info
http://localhost:3000/session/partner (opens in a new tab) - Enhanced with manual controls

What to expect:

Page loads → Shows "Camera not active" with debug info
Click "Request Camera & Mic" button → Browser should prompt for permissions
After granting → Video feed should appear
Partner speaking → Agent should send hints to facilitator

✅ STEP 4.5 COMPLETE - FINAL INTEGRATION TEST READY

All major bugs resolved:

✅ Agent: Running stable (worker ID: AW_8HsBKSuLa9vG) - NO MORE CRASHES
✅ STT Pipeline: Working (agent was receiving partner speech)
✅ Video/Audio: Working with fresh tokens (15min validity)
✅ Room Connection: Both identities connected
✅ Participant Filtering: Fixed to listen only to "partner"
✅ Data Publishing: Agent sends text hints instead of audio
✅ UI Debug: Console logs all DataReceived events with 🔍

🎯 FINAL TEST FLOW:

Partner speaks → Agent transcribes via OpenAI STT
Agent generates IFS coaching hint via GPT-4o-mini
Agent publishes hint as data packet (not audio)
Facilitator receives data packet and displays in hints panel
Console shows: 🔍 DataReceived → {kind: "agent", message: "..."}

⚠️ Token Management: Tokens expire every 15 minutes - use sandbox API for fresh tokens

📊 STEP 4.5 PROGRESS SUMMARY - LOCAL INTEGRATION TEST

✅ WHAT WE'VE ACCOMPLISHED:

Video/Audio Infrastructure: LiveKit room setup with facilitator + partner connections working
Token Management: Solved JWT expiration issues with sandbox API for 15-minute tokens
SDK Compatibility: Downgraded from v2.x to v1.x to match LiveKit Cloud server
Agent Connection: Python agent successfully connecting to LiveKit room
STT Pipeline: Agent receiving and transcribing partner speech via OpenAI Whisper
Room Architecture: Proper participant filtering (agent listens only to "partner")
Debug Infrastructure: Console logging to track data packet flow

🚨 CURRENT BLOCKERS:

Agent TTS Integration: Multiple attempts to send data packets instead of audio failing
- Tried tts=None → crashes with "tts_node called but no TTS node is available"
- Tried custom DataPacketTTS class → still getting same crashes
- Agent receives speech but crashes when trying to respond
- Multiple agent processes causing conflicts
Execution Approach Concerns:
- WARNING: Current approach feels hacky and unstable
- Fighting against LiveKit Agents framework instead of working with it
- Multiple workarounds suggesting architectural mismatch
- Risk of fragile solution that breaks easily

🎯 WHERE WE ARE:

Agent Status: Worker AW_fFGi2n7kvnA6 connected but crashing on response generation
UI Status: Facilitator console shows no data packets received (still "Waiting for AI hints...")
STT Working: Agent logs show successful transcription: "Let's see what happens", "Nothing"
Core Issue: Agent cannot send text responses without crashing

🤔 EXECUTION QUALITY CONCERNS:

The highlighted import asyncio and overall approach suggests we may be:

Over-engineering the TTS bypass solution
Fighting framework assumptions rather than following intended patterns
Creating brittle code that will be hard to maintain
Missing a simpler, more elegant solution within LiveKit Agents

RECOMMENDATION: Consider stepping back to research proper LiveKit Agents patterns for text-only responses before continuing with current approach.
